I really, really enjoyed the episode on the whole. I thought everyone did a great job and Gaius was put to good use. I really liked the ending too and I like that Aggravaine managed to bring everyone closer together by forcing them apart. It showed everyone what they all meant to each other. I have an awful feeling this is all leading up to killing Gaius off, but am enjoying his relationship with Merlin in the meantime. I like that he has more faith in him and Merlin doesn't hesitate to go after him.
