I am never not thinking about hardison and eliot looking at each other while parker changes in the elevator and turning away once it's immediately clear the other dude's spooked too

I see we're going ape over buddie and Choices tonight so

Yknow in 2.07, when Shannon comes back and her and Eddie have their first scene together? The argument at the end, after Eddie says it wouldn't be a good idea for her to see Christopher bc she left them, she says she needed him, she needed a husband and a co-parent - and "I needed someone to have my back!"

To which EDDIE says, "I always had your back"

*insert Incredibles "coincidence? I think NOT" gif here*

(Also side note, I do like that the show doesn't try to sugarcoat what Shannon did being messed up, and that Eddie's own actions weren't really the right thing either[thinking about his conversation with Buck where he says he got to pretend he left for a noble cause even tho he was running], and that it was just a sticky situation that neither of them were equipped to handle in any way, and snowballed. I do kind of wish we could've gotten post-divorce Shannon and Eddie and Christopher interactions, figuring out how they fit together, if at all, bc I like those intricate and messy situations but I could see how that might get too close to retreading old ground re: Michael and Athena's divorce. But I do hate how ive seen the fandom like. Seem to oversimplify things with Shannon sometimes? And make her the ultimate villain, and Eddie Did Nothing Wrong, Ever)

Hi Anon!

The decision to have Buck and Eddie's first bonding moment end with "You can have my back any day" and "or, y'know, you could have mine" only to then six episodes later find out that at least a contributing factor to Eddie's marriage dissolving was that he "didn't have her back" is like. Such a galaxy brain chaos move for them to take, honestly. Like?? They could've had the phrasing be literally anything in 2x07 but instead they had it directly echo Buck and Eddie in 2x01. What was the reason? Why did they do this?

As for the rest of your ask:

(gosh this got long and, uh, opinionated. It is Not Pretty below the cut)

One of the things I really liked about Eddie Begins is that we did get to see him at the beginning of his journey in being Chris's dad because it gives us an opportunity to appreciate how amazingly he's grown as a father. Like, he didn't start out as a perfect dad and he was definitely kind of lost in the woods at the beginning there when it came to the whole "how do I parent" thing. And before Eddie Begins, we'd only ever seen the end result of the growth he's gone through, where he really is a fantastic dad whose son is basically his entire reason for being. Before Eddie Begins, we get to hear him say things like "I left first" and "I've failed that kid more times than I can count but I love him enough to never stop trying" but we kinda have to take that on faith? Because we hadn't actually seen him be anything besides a good dad until we saw his Begins episode. (And even then in his begins it's like "area man in his early 20s unsure how to care for small child while also coping with PTSD and a toxic support system" which like. yeah. no shit. there's one hell of a learning curve there)

The thing about Eddie and Shannon as a couple and as parents that always gets to me is that they were so fucking young. We don't know exactly how old Eddie is in the show, but we can guesstimate pretty safely that he's around the same age as Ryan which would make him between 23 and 24 when Chris was born, and it seems reasonable to believe Shannon was around the same age. It's also a pretty common reading in the fandom -- although I'm not sure how much canon support there is for it because we really, really don't know anything about their relationship pre-Christopher unless I'm forgetting something -- that they got married because Shannon got pregnant and that was the Done Thing. And when you're 23-24, baby on the way, freshly married, that is just like. So much. It sure as hell ruined my parents' relationship when they did that exact thing, and then they disliked each other until they were 27 and then they got divorced, and no one was happier than me about it, I have to tell you.

Back to the show, I can only give you my impressions, obviously, but the impression I have always gotten from the whole "I left too" conversation and the context that goes into it and the different behaviours we see exhibited by the characters is that Eddie "left" first and it comes across to me that he was basically an early twenty-something kid running scared from the abstract concept of being a father in general, and then when he was forced home by an honourable discharge, and was confronted with the reality of Christopher, he managed to step the fuck up and become Christopher's dad. It's there in 2x02, right? "Oh, you've got a kid? I love kids!" "I love this one." Eddie doesn't strike me as a Swiss Army Knife all-purpose Dad(tm) the way Bobby is. Eddie is Christopher's dad. (and like, of course, he's obviously moved by kids when he's on a call, we've seen that enough times to know that if there's a child who can even glancingly remind him of Christopher, Eddie's sense of self-preservation goes out the window, and I love that about him as heart-stopping as it can be in practice)

Shannon, on the other hand, didn't run from the idea of being a mother -- at first. When she left, it wasn't from the abstract. She left Chris (and "gave up" on Eddie, thanks Helena). She was not running from a concept, she was running from a reality. I think Shannon is a fascinating character to include in a television show as a side character, because she really isn't a one note character. Like, she was unarguably a bad mother, and from what we saw, she was a questionable romantic partner to have (but as you said, anon, Eddie was also not 100% the best romantic partner when he was with Shannon either; their entire relationship so far as I can tell was built on sexual chemistry which, uh, super does not sustain a relationship), but she also seems to have been a devoted daughter? I mean, yeah, it's entirely possible that her mom being sick was a convenient excuse to bail -- and obviously she didn't come back after her mom died, and didn't, y'know, contact her son or husband in the interim, so yes, I can see that being a valid way to read the situation. I don't think she's the Ultimate Evil, because she strikes me as a very human character in all the ways that people are more often than not really fucking flawed.

But then we get back to the actual break-up scene. The first time I watched it (and second, and third; then the fourth time the person I was watching with was like "I mean, sure, but it could also be read in this light") her "I'm just learning how to be someone's mother" speech really bothered me? Partly because it was the abstraction of it, right? Eddie doesn't like kids, he likes Christopher, and Shannon sort of had the inverse journey there, I guess, where it went from she didn't know how to be Christopher's mother, to she didn't know how to be a mother. And that speech bothered me because it always sounded to me like she was bailing again. She begged Eddie to let her back into Christopher's life (guilt? I guess?) and like, straight up bribed him with sex which was sure a choice, and then decides -- for a second time -- that she's out. It sounded, to me, she was handing Eddie papers and maybe, in a few years, possibly, once she'd had "time" to "figure out how to be someone's mother" she would try again. Just like she had in the interim between leaving when Christopher was little and the time of season 2.

And like, that could totally be a misunderstanding of the scene and what she was saying. It's what I took away from it, but that could very well be influenced by the fact I was raised by divorced parents and my dad had custody and if you count up all the time I spent with either parent when I was a minor, I was predominantly raised by my father and have had an especially tempestuous relationship with my mother that is mostly (sometimes) repaired now that I'm in my late twenties and have not lived with her since I was sixteen.

Back to the show, and to your comment that the fandom tends to treat Shannon like the Ultimate Evil and act like Eddie Did Nothing Wrong, I mean. Yeah. Fandom as a rule tends to shirk nuance. We're all fools here on the internet sitting in our blue industrial waste container crying about a wee woo show. I personally believe a more nuanced take on that might be that Eddie has shown a great capacity to learn from his mistakes (sometimes to make fun, shiny, new ones, but for the most part, just like ends up doing better the next time) and Shannon did not show that capacity in the time we knew her.

I think, depending on what they did with it, there was potential for an interesting storyline if they'd played through the divorce. I don't think it would've been rehashing ground covered by Michael and Athena's divorce because I can't see Eddie and Shannon having reached a point of amicability and friendship. The only thing we know they had in common was Christopher, and frankly, when you boil it down, the ways they engaged with Christopher as a person were so disparate that -- to me -- it really didn't seem like they had Christopher in common when you get right down to it. But I wouldn't have wanted to see Christopher and Eddie dragged through an ugly divorce process. They deserve better than that.

There's also a conversation to be had about Shannon's blatant ableism towards her own son, but that is extremely not my lane since I am not disabled myself. But even from an outside perspective, basically their entire parking lot conversation in Haunted, uh, haunts me with it's repugnance and the fact that instead of calling her on any of it, Eddie "Chronically touch starved" Diaz's response was to kiss her? Gosh golly do I wish that was one of the mistakes he learned from properly instead of finding a new, shiny version.

ANYWAY this got long, tl;dr (although if you clicked on the read more, you probably read it) version is No, Shannon is not the Ultimate Evil, she's a shitty mom not a demon in a skin suit and a pretty yellow sundress; and No, Eddie is not a flawless human who's never done wrong in his life but holy fuck is he trying and he'd be the first person to tell you he's made mistakes (and often has been); and no, sorry, I don't want to see the divorce storyline play out because we probably would've had to see either Eddie Bashing, Shannon Redemption, or Shannon turning up again like a cardboard cut out of a cartoon villain the way Eva did and I want to be witness to exactly zero of those things.
