There's a remark on the tip of Jeff's tongue, but. Now's not the time, not the place, for levity, especially when Bash is so... distraught. He's already making such little sense as it is, and Jeff would be a piss-poor partner if he wasn't concerned--

"C'mon, it's not like I'd be the first one to ride him!" he calls after Bash.

...fine, fuck it, okay? Bash set him up for the punchline. He couldn't just leave it hanging! And anyway, far as anyone else might be able to tell, it's just a little lovers' spat.
