During his first couple of weeks here, they were fighting large problems together and making progress on them together. Now it's more - split up, Keltham working on chemistry, things in the Project feeling more routine, they're both still working but they're not fighting together the same way. Carissa being tied to a bed - doesn't always give her the same chance to, impress him, maybe. It's not exactly the right word, but -
Of the things she's described, her watching his magic practice and giving him extremely Spellcraft-loaded advice sounds closest to being right, to him. It's something they can work on together, succeed on together, and someplace where she can remind his brain that she's Carissa Sevar. It's - maybe something for him, like his being dangerous is, to her, that she's got ludicrous Spellcraft. Not just that she's a valuable possession, but that she's - somebody who could have had the Queen of Cheliax, if Keltham hadn't gotten to her first.
