Continuity mistake: Right after the Hawker demon attacks, Piper picks the baby up and the head of the doll is covered and you can't see the face; a quick change in camera angles shows the baby's face and the blankets are all arranged and folded to frame the baby and no time has elapsed to allow this to happen. Also, the doll used as the baby double is much smaller than the baby and is very noticeable in shots that switch back and forth between the covered doll and real baby.

Plot hole: When Gith takes the potion from Chris, he ends up stomping on it and shattering the potion bottle - making contact with the potion. We've seen that potions don't have to be thrown by someone who's even a witch for them to work (like when Cole's powers were stripped etc) so why on earth would he do this? And how did it not vanquish him? There are other ways he could have gotten rid of the potion that didn't involve a way that really should have vanquished him.
Cole: Phoebe, I love you. I don't know what's going on but maybe I can help. Would you like me to kill someone for you?
