Okay Sam, fine, proceeding with caution Looks like a no if you don't recognize me. Name's Jo, your twin up there is a friend of mine. We have a lot of Sam Winchesters here and we've done tests, no shifters or demons among them so far. If you want to meet up and do those same tests I can vouch for the others and, you know, see if you're who you look like and see if you try to kill me in which case I will have backup.
