A wry smile crosses his face at the mention of something living in one's head forever, since - that also feels familiar. There's no particular comfort Claude can offer there; some things simply change too much to ever be fully erased no matter how long it's been since they happened. He can think of several of his own in a matter of seconds.

The rest of what Abby says seems to clarify a bit more of what's going on as he thinks about it, and after a pause he nods slightly to show there was some consideration happening in the silence following rather than just letting them go without a response.

"That's fair enough. Sometimes there's benefits in pretending to feel or act one way despite feeling the complete opposite, but that doesn't mean it's right to apply to it to every situation and especially those where you're uncomfortable. The same goes for hanging around with someone when there's far more Summoned here. Besides Cadens alone, that is, since that's true across the other places as well and when you factor in the Horizon? More than enough space to look for those you feel are worth getting to know."

Though, with a tilt of his head and a slightly more genuine smile, "Not that it makes it easier to have to start over or any more fun to do since that part's kind of universally terrible, I've found. But sometimes that also means it's a chance for you to find what you do want out of it, too."
