Watching Jack's movements closely (he hasn't seen him in months, though it felt more like an eternity), Akito thinks something is wrong, but can't be sure. Interdimensional travel takes a bit of time to adjust to, after all, so it's likely that's the issue at hand. "Are you alright?" It doesn't hurt to ask anyway.

"And... Ah, I'm glad! Even if you're different, you're still Jack Frost. Guardian of Fun and shepherd of winter! One of the best people a person can be fortunate enough to know. And there's nothing to make up for!" This is one thing Akito tries to stress, though it's difficult to sound stern when you can't stop grinning. "Almost everyone forgets Adstringéndum once they leave, so even if I succeeded in following the Jack I knew to his world, he wouldn't have remembered me either. It happened once before."
