If you told us at the beginning of Grey's Anatomy Season 10 that Arizona would be hooking up with intern Leah, of all people, we would have had a hard time believing you. OK, not that hard a time, since bed-hopping is a Grey's tradition, but it certainly wouldn't be the first pairing to jump to mind.

Still, it's happened, and based on the very end of last week's episode, it's going to happen again. Already, it seems like a recipe for disaster. Arizona is hurting and lonely because of Callie, and Leah is an easy source of solace for her. That would be fine, if it weren't for Leah's clear track record of getting way, way, way too attached quickly. As it is, the combo could be very combustible.

Still, that's not necessarily a bad thing. Actually, we're surprised to say we're kind of intrigued to see how far this fling will go, and what will happen when it meets its inevitable end — and we're pretty sure the end is inevitable. We definitely can't get behind this pair as a viable long term relationship, both because we think Arizona belongs with Callie, and because we don't see why Arizona would be that into Leah, even without Callie in the picture.

But as a source of drama? Yeah, it could work.
