Liked the flashbacks of Emily with her sister and her bonding with Mike.
Some of the insults were lame, but the one-liners worked better this time.
I like how the Nighloks actually harm civilians and cause accidents. Would be nice if they'd bother to explain they grow by getting a second life.
Some of the acting is still pretty wooden, but this was a good focus episode for Emily and I'm quickly getting to like her. 4/5
