On PT during the Tell Nothing, Michael and Sarah say they were married 12 years. in PT land, Veronica says to Tim, " Huh, same as us. Not that we're married."
I remember somewhere back in this thread or elsewhere on the interwebs, someone posted some podcasts from Timmy from a few years ago, and I heard him call Veronica his wife 5-6 times.
Doesn't mean they are, but more grist for the mill.
