Yea, as someone said above, "I thought it was just me".
C'mon, we all know Quinn isn't going to die (otherwise he'd have been killed off in this episode) and Saul will reveal to Carrie at the beginning of next season that appearing to go along with Adal is really a super-secret plot to unmask him.
Frankly, I got a bit excited when I thought, just after it appeared Carrie would succumb to Quinn's charms, that Adal was going to have Quinn killed. That would have been the old "hero can't find happiness" theme, a sad but at least involving ending.
But we didn't get even that (I mean: "Why did Quinn change his mind anyway?").
