Effy. Kate knows the name and face but not the girl. Lost a bunch of people, went a little or a lot crazed, Finnick and Kate and some others have been looking out for her since. Stuff exploding, that's probably mostly Marshall but a lot of people went missing around the same time as Declan.

"Yeah, I know that feeling." Rapture's a good place to 'do something'. It's just what sort of 'something' Kate has in mind. "Sightseeing, window-shopping, treasure-hunting or adventure climbing? Rapture's got a little bit of everything, even if it's mostly defanged." Kinda like Tesla, really. More a memory of danger than actual danger, but sometimes it jumped up and bit you anyway.
