[Shockingly, the implication that Aziraphale could physically overpower him does not help with the 'I hope this doesn't awaken anything in me' problem, but if the past couple of millennia have taught Crowley anything, it's how not to get distracted by how he feels about Aziraphale.]

If I didn't know how to handle someone more powerful than me, I'd not have lasted those first few years in Hell.

[It's an underhanded tactic, to use this particular argument, because it just so happens to be something he doesn't ever talk about, especially not to Aziraphale. When he talks about Hell, it's to complain about paperwork or assignments or Hastur popping up announced. Sometimes he'll mention the threat of Hell, but he never talks about how bad it really is, or what it used to be like.

So this is brand new information, offered up on a platter.

He draws his legs up to sit cross-legged on the sofa, as if settling in, getting comfortable.]

Don't forget that I'm good at my job, Aziraphale.

[For all the laziness and complaining, when he sets his mind to it, he knows how to tempt someone, how to convince them to just give in to what they want.

What Aziraphale wants is to feed, and Crowley knows him better than he's known any human he's tempted.]
