Raf doesn't really get anxious before a show, and genuinely enjoys performing on stage--but the most difficult part of a performance for him are the hours right after a show has finished, starting from the moment he walks off the stage.
Almost every single time, no matter how fun or well executed a performance was, there's a kind of quiet terror that follows him off the stage like a dark shadow and infects him once he's left the safety of the stage lights.
He becomes uncharacteristically furtive, and while he will answer when spoken to, his responses are simple, short, with a kind of sharpness in tone that suggests a level of defensiveness. Like a child awaiting a harsh scolding. Because that's kinda...what he is, in that moment. He is waiting to be kept awake into the early hours of the morning by a lecture about what he did, what he didn't do, what he should have done differently, what needs to be improved upon before the next time. Or he's waiting to be told that he's gonna be on his own for a few days, because the people who are supposed to love and take care of him are "too disappointed to fairly manage him" right now. Or he's waiting to be dragged into a busy room populated by strangers he's supposed to impress while he's casually, conversationally picked apart in front of them by the person who brought him there in the first place; the person who wanted to show him off.
It's a frustrating reaction to have...He's not a child, he's a grown ass man--and he owes venue staff, and his bandmates, and everyone else backstage a modicum of respect and kindness, and to thank them for their work, and to revel in the completion of a good show. But he's not really...he can't do that. He comes off as quietly despondent at best, or kind of a stuck up asshole at worst. When he did shows with Lacey, she called it his "post-performance tantrums" and exercised very little patience for his 'immature sulkiness' following concerts. And the low mood would persist for a solid week then after.
Once he started doing shows and stuff with Margie, she'd initially wonder if his poor mood was because she had done something wrong, or didn't meet expectations, if it was a bad show.... It wouldn't be until the following day before Raf could find himself in a state of mind where he's able to explain what he's feeling, much less why. And...for whatever reason, he's reticent to offer the most simple explanation to her--because saying "it's a ptsd thing, just give me space and patience and don't take it personally because it's nothing to do with you" comes with the risk of being asked other questions about himself and his upbringing that he's not comfortable getting into and--it's a whole thing, in his mind. So the first few shows together are consistently...a bewilderingly negative experience for Margie, in that it's a very tense, quiet, insecure and shame-ridden 24-48 hours after the show--followed by delayed revelry days after the performance with Raf finally able to reflect positively upon the experience and assuring Margie that it actually was a great performance, and that he had a lot of fun--and they're able to recall their favorite moments together, etc.
Unlike Lace, though, Margie never digs into him about his behavior. She just mirrors his silence, and then--very uncomfortably--gives him space because she doesn't really know what else she can do, and--assuming she's the problem--she doesn't want to risk messing things up even more, since she doesn't know what she did wrong in the first place. And, you know, there's only so many times Raf can reassure her, too late, that she was great, actually. And so he finally does relent to telling her that this is just...how he is after a show, that it's no one's fault, he's not mad at her or anyone--it's just ptsd. That's all he tells her, and, as per always with Margie--she doesn't try to pry out more information from him about it.
Margie goes down her own little rabbit hole of research instead, and comes to Raf with the idea for a new post-performance routine (communicated with staff and such before hand to ensure accommodation) wherein they don't try to gladhand, or pack up, or do literally anything for the first half hour after they walk off stage. Instead, they find a quiet, dimly lit corner somewhere away from everything and just sit, and rest, no expectations, no obligations, nothing. Raf agrees to put this idea into practice, and it quickly evolves into, well idk... Being held and gently rocked like a child by someone who means something to him.
