A Minute For Brothers & Sisters

I'm assuming Justin and Rebecca will date once it comes out that she's not a Walker. However, in real life, wouldn't that be too much to overcome? Would the Walker family really let that relationship happen? Though they're cute together and the audience likes them as siblings, how will America take to them being a couple?

Just thinking out-loud and readying myself for the potential awkward television that will be their relationship.

Any thoughts?
