okay but imagine if shadowhunters had had filler episodes. just them doing dumb nonsense that didn't have any effect on the plot. bonding.

clary learns about the nephilim education system and she doesn't know whether to be horrified or amazed cause on the one hand they're giving knives to four year olds, on the other hand, izzy is a fully certified forensic pathologist at 19.

simon spends an entire episode dragging raphael around new york tryna find him a replacement jacket because even though the kidnapping situation was very fucked up he feels really bad!!! the episode ends with them picking out a really amazing jacket and then raphael having to pay for it because with all the supernatural crap happening, simon honestly forgot that he's a broke college student.

jace and alec episode with them on their day off just chilling (izzy and clary following them because clary Does Not Understand Parabatai and izzy thinks this will help. somehow.) they go to the library and spend some time curled up together reading. they get coffee and go to the park. jace screams at some ducks while alec provides moral support. they go for a movie. they walk around the city holding hands. they go back to the institute to spar a little and then head off to bed. clary through the episode keeps asking "are they dating? are they not? seems like they are?" but izzy keeps denying the dating allegations. clary then finds someone in the institute that can actually explain parabatai with actual words and she barges into izzy's room in the middle of the night screaming "YOU COULD HAVE JUST TOLD ME THEY'RE SOULMATES ISABELLE!"

there's an episode that is literally just. magnus' cats. nothing else. magnus provides narration like this is a nature documentary.

malec's second date, where they just sit on the couch and watch tv and trashtalk the characters. the entire episode is edited to look exactly like a youtuber-reviewing-a-tv-show thing. the first time time an action scene comes up, alec gets so mad at how unrealistic it is and magnus gives him a detailed explanation of how and why movie fighting is so different from real life fighting and why they're choreographed that way. the episode is an hour and a half because magnus and alec keep getting sidetracked and start talking about random stuff. it ends with them falling asleep together on the couch.

a magnus & catarina & ragnor episode with them just hanging out. cat and ragnor keep making fun of magnus for being so in love but he keeps agreeing with them with a lovestruck expression and that takes the fun out of it. the episode is a clipshow style thing except it's not clips of stuff we've already seen, it's their adventures (including, obviously, peru.)

a jimon episode where simon sits jace down and explains in detail the entire plot of star wars. all the star wars. jace asks so many questions and they get so sidetracked at times but simon powers through. at the end, jace reveals that he actually has watched star wars and he knew everything simon was saying but let him go on and on for hours because he wanted to see whether simon would figure it out and also cause jace likes spending time with him.

a clizzy episode where izzy jokingly asks clary to paint her and clary gets so excited!!!! so izzy goes along with it. clary keeps talking like she's doing a tutorial on painting except izzy can't see what she's doing. through the episode, izzy keeps doing more and more ridiculous poses and clary paints and sketches them and somehow they turn out actually good?

i have more ideas but like. idk about you guys but i'd have watched the hell out of this stuff.
