When Mordred tries to stop cuddling Lev, still close enough to stop Lev if he tries to stand up, Lev has hallucinations about mouths and monsters and Dr. Keaton and Samson Trammel and something that Mordred can't tell what it is because it's in Yiddish. He screams and cries and pleads incoherently in several different languages.
So Mordred... accustoms himself to the idea that he's going to spend the next couple days in bed with Lev. Gets Agravaine to bring them food and water, which he does with a minimal amount of eye-rolling. This is both easier to deal with and, on another level, immeasurably harder for reasons he does not feel like examining.
When he's being held, Lev is happy and says "love you" and "you're pretty" and asks Mordred to read to him and also asks him when he can go to the library or when class is or whether he should be working on his thesis and occasionally propositions him for sex. "No" is usually fine when it is from George and terrifying when it is from Echavarria. Mordred tries switching from "no" to "maybe later," which is much more likely to result in Lev making happy noises and trying to curl up on his thigh and much less likely to result in Lev crying and begging Mordred to tell him what he did wrong so he can fix it.
Lev shakes and trembles and throws up more food than he's capable of holding down; he complains about light and noises and pains all over his body; he sweats and he's uncomfortably pale.
