UNCLE CHARLES LOVES YOU VERY MUCH KURT no seriously, Charles finds Kurt to be a joy to be around, most of the time. He really appreciates Kurt's happy-derpy-puppy-ness because it lets Charles indulge in that side of himself as well. The "most of the time" caveat is that sometimes Charles is really just Not In The Mood but doesn't want that to show through, particularly to someone as nice as Kurt, which turns being around Kurt into a rather draining exercise. (Though that's not something particularly specific to Kurt -- it can be a strain to be around just about anyone at some point or another -- Charles does feel a little more walking on eggshells with the Evo kids, since their future seems less horrible than everyone else's and Charles doesn't want to, like, break that or whatever.)

AS FOR MYSTIQUE Charles will not be telling Kurt the details of that anytime soon. But he does feel even more responsible for Kurt now, though it remains to be seen if that will manifest itself in any noticeable ways. Even though there's the whole alternate realities thing going on, Charles still feels a little guilty, because whatever happened to Kurt because of Mystique (and, with your OOC permission, Charles will be checking that out at some point without telling Kurt) somehow links back to Raven becoming Mystique in the first place, which, if Charles hadn't failed her and lost her, would not have happened in the first place.

Also, Charles just doesn't want to think about his little sister getting knocked up. >.<;;
