Continuity mistake: Just after Olivia has killed Mr. Montana and everyone goes running up to see what has happened, Phoebe waves to Paige through the window of the Calloway's house which is shown to be right next door to the Montana's house. Earlier in the episode it had been established that they lived across the street.
Factual error: When Phoebe was telling Paige that the energy ball did not come from the other house, Paige says she saw it come through the window. She could not have seen it because she was in the other room and the door to Richard's dad's office was closed.

Continuity mistake: When Chris orbs to the manor after Paige has returned home, his hair is brushed to lay mostly flat and behind his head, with a part on the left side of his scalp. When he comes into the kitchen shortly thereafter, his hair is shaggy and unkempt, with a part in the middle.
