Oh, no worries, it's always fun to read up on a new canon, especially one this complex! I like the art for it too!

I don't mind diving straight into a memory to get them started. I like the cat idea (cute!) since he's seen it and true, he doesn't know it's hers, but he could maybe guess based on the three people who run Affurgato that this memory he's seeing is one of theirs? Was there a memory you were hoping she could regain through the event though, even if bittersweet or not that great? I wouldn't want you to lose out on that too if you were hoping for a regain!

And I'm all for tragic memory stuff on his side to make it fair too! Being alive here means more time to think about his past, so the obvious one is when his parents die, if you're up for that kind of thing? How she'll find out it's him, not sure, but we can leave it up as an accident too, like while he sends hers back to her without knowing she's going to send his back to him?
