Have you written anything about what Lisa says to Dean when he’s under Veritas’ curse? How much do you agree/disagree with what she said to Dean? I’m interested to hear your take.
I've never written anything about it. I'm 6 episodes away from "You Can't Handle The Truth" on my rewatch though, so. I'll wait to get into it much until then. More generally though, a lot of what Lisa says is based upon her assessment of Vampire!Dean showing up the previous episode.
WE as the audience know that Dean was a vampire. Dean thought he was going to have to die (because he didn't know about the cure for vampirism yet). He showed up to say goodbye to Lisa and Ben and thank them for everything they did for him before asking Sam to execute him. When he felt tempted to eat Lisa and Ben, he started stumbling out and away from them, making apologies about putting them in danger (and this did include some actual spiraling thoughts about how bad he is for them and how he's going to die—but pretty reasonable considering he's a newly-turned vampire and thinks he's going to die).
From Lisa's perspective though, the Dean who showed up at her house wasn't a vampire. The Dean who showed up at her house is just what happens when someone who's been coping with PTSD for over a year goes back into the field because his brother returned from the dead. From her perspective, Dean showed up freaked out, out of the blue, having a PTSD-fueled emotional spiral after re-entering a war zone he wasn't equipped to re-experience and that point blank—requires shoving down emotions he cannot successfully bury anymore. Dean could not cope with hunting again, he showed up freaked out because he tried to hunt when he couldn't emotionally handle it, his thoughts spiraled, he broke up with her (that's how Dean's dialogue in 6.05 sounds if you're Lisa) over something (from her perspective) they had already communicated about/talked through (but now all of that is in the wind after Dean returned to hunting). Then in his panic and distress, after refusing to sit down and talk through his spiraling thoughts with her (because he couldn't cope with bringing them to the surface) he lashed out and shoved her kid in a panic.
Everything Lisa says in 6.06 is colored by that assessment of 6.05. It doesn't make everything she says entirely wrong, but it's important to allow it the context it's based upon and acknowledge that that context is somewhat skewed.
