[When Lyn spots the box for him on the table, he's actually kind of wary. It...can't be a regain, right? Nothing's gone tits-up recently, so unless Mayfield has started handing things out for free - which would be awesome, but super unlikely - it's gotta be something else. Probably something completely horrible, like everything else the town drops on them unprompted.
...the problem is that Lyn is way too damn nosy for his own good. No amount of caution could stop him from opening the box unless the box was weeping blood or had a logo for the Rabid Rats Emporium on it. So, after only a few moments of hesitation, he tears into it.
And freezes.
No...no, no fucking way. There is not a single thing in his head right now that makes any kind of goddamn sense. Not what he suddenly remembers, not the fact that he ever forgot, not the fact that he didn't just punch Legault in the fucking stomach at some point.
Man, he'd...he didn't care about people like that. Not ever! It was stupid and sappy and everything he didn't want or need complicating the fuck out of his life. But somehow he'd lost his fucking mind and wound up with Legault, and - and okay, just own up, it had ended just as badly as he should have known it would. And...oh, god, now he's stuck living with Legault. Yeah, this isn't gonna get fucking awkward at all!]
[The fact that these new memories memories don't really fit with logic in general - like how he'd ever been to Legault's world, or how Legault had been to his - isn't something Lyn is taking into account right now. He's way too wound up. Instead he stalks to the bottom of the stairs and bellows up them.] Yo, Legault!
