I don't think I have. I'm going to the bookstore on Friday, so maybe I'll look for it. ( he points to his wheelchair then. ) But join you in the shower with this? ( he smiles at erik, amused, but adoringly so. ) Maybe if Hank ever gets to finishing that serum he keeps harping on about, I'll get the use of my legs again someday. ( they've had the talk about whether or not the serum's a good idea since it's experimental and risky, but charles is adamant about giving it a try if hank ever gets it finished. he wraps his arms around erik then and presses a kiss to his cheek, and then once more on the tip of his nose before giving him a good and proper kiss. there's so much he wants to do with erik, really, but there's limits to what he can and can't do, and what he wants to do even, but he thinks they're managing just fine so far. )
