[He knows that tone well enough, forces himself stop and pay attention, hands settling lightly on Aziraphale's chest. This is important, he knows it is, it's just difficult, too.]

I wouldn't. Hold something like that against you. M'well aware it's outside our control.

[Not that he's actually slept with anyone aside from Martin and Aziraphale for a while now. Since the last time with Lyall, but he hasn't forgotten how it felt in the aftermath, realizing he hadn't had full control of himself, and he'd never blame Aziraphale for anything that happened like that.]

And I'm not threatened, I know you're not about to run off with anyone else. [He does, logically, although that doesn't stop the anxiety. But the fact that Aziraphale is asking directly for the truth means he has to give it, it wouldn't be fair not to.] I was a bit jealous, I guess. Doesn't have to be a big deal.
