Wuffenloaf - S3-E1
Plot hole: When Abby and Eric return the night vision goggles, Abby asks if they should put them back exactly where they were and Eric says he didn't remember where they went but luckily he "took a picture" of how it looked before. How could this be possible if Abby purposely excluded him when she collected those goggles from Lisa?
Plot hole: Gary is still "alive" because his head/brain was not destroyed when Shiela killed him. However, over the course of the show, we see many bodies in the freezer or otherwise with the heads still intact yet none of them are still "alive" in spite of the fact that their brains have not been dispatched.
