Why haven't they injected the plot with millions of lesbians yet? Fangirls would stop foaming at the mouth in outrage of potential coupling. *snicker*

Hahaha, not to mention that it'd just be awesomely hilarious.

And yeah, kind of a plot hole there. I mean, they can touch Bobby and have access to his whole past. They can possess and angel and know every alias that Dean and Sam ever used...but they don't think to copy Frank for the password? *rolls eyes*

Maybe they sent the lowest of leviathan lackies to kill Frank and they foolishly ate him and then thought "oh hey...maybe we should see what's on the computers...oh damn." :P
