At this point? Disbelieving shock. A whole ton of regret because Gokudera remembering means facing again how badly fucked up their relationship in Sabra was, and how legitimately close Zexion came to destroying Scowl's heart rather than dealing with it.

Part of him would want very desperately to hug Gokudera and just not let go, and another just as powerful part would be frozen, knowing that he still doesn't have the right to do that until Gokudera returns that right to him. Which would depend, a lot, on what those memories were.

If they weren't of Zexion specifically, he'd probably just . . . be quiet and a little shocked, but pretty . . . nonreactive. Sad, but in a lot of ways he's accepted that being a Nobody is bound to mess with being remembered, and it's . . . okay. He'd hope they were memories of Yamamoto, at least, to balance out all the experiences with River.

If they were something of Zexion himself . . . granted, knowing Zexion's luck, if Gokudera remembered him specifically rather than camp in general it would probably start with something like . . . man, when he rescued Gokudera from Dietrich and kind of shuffled through all Gokudera's memories of hurt and humiliation, but.

Even then.

Hugging and disbelief and probably damp eyes if not full-out tears. And quiet but a very, very heartfelt apology. Again. Because remembering doesn't make things okay. It . . . means there's another way they can relate, but remembering something from that time doesn't make Nova Gokudera any more than being remembered makes Zexion a Nobody with an attachment problem.

But it's closer.

How would Gokudera react to meeting another of himself here?
