Alright, let's do it!! But because I always overthink time travel stuff help me out: since they retain the knowledge from the time rift shall we say the way he learned of her past was different in that future? As in, in that timeline she gradually opened up while getting therapy, so this dream revelation will be new and unexpected (but he'll still know about her past as such from the time rift, so they both can brace for it together at least)?

I'll see if I can whip up a mayo factory dream! Or what would LB's nice dream be? That might be interesting too! Comforting her takes priority for Hijikata since she's the one with the nightmares.

I'll make Hijikata see it through too!
