Re: Jimmy/Jenny - where do you stand?
It'd be an eyebrow-raiser to me, to be sure, but not one that would likely bother me too terribly much.
What WOULD bother me is if they pull the "Jimmy's sibling/cousin/whatever" schtick with her, though. "Smallville" might have gotten away with that, but that doesn't mean it should be repeated.
