Rereading parts of Tonic and Fever to maybe do some light editing/start outlining the next chapter, and man... they really are cute... in ch4 especially...
Vezrik doing whatever he can to get a palpable reaction out of Alluvion because he's petty and annoyed that he has these pesky biological imperatives for Alluvion to manipulate, and Alluvion doesn't (at least, not in the ways Vezrik is used to)
Alluvion getting embarrassed when this does, in fact, happen, when they were so zeroed in on taking care of Vezrik
Vezrik getting into it and saying things like "if you stop I'll die" and then reassuring an amused Alluvion that it's hyperbole, "but don't test it!"
(Honestly, all the banter they have in this chapter is really satisfying to reread. Tooting my own horn but the characters I created to have chemistry have chemistry. :v)
Alluvion thanking Vezrik as if he's done them a favor, which Vezrik finds a strange concept, but as soon as he privately acknowledges that maybe it does mean something important to them, he must hurry to shove bread sticks into his purse remind himself that it's not gonna be his business anyway because he's definitely leaving and not coming back, right now
