There's a note at the bar for Gil. That Piper would have left..before she went through the Stargate. That the mun forgot to put up. Because she's forgetful like that.
Gil-
I'm sorry but I have to go fight the bad guys and save the world or something like that.
I promise I'll get to work when I get back~
-Piper
At least she can actually tell her boss where she's going this time.
