The case itself was a good one. I really liked the way that Charlie found out where the hostage was located, thought Im very surprised that he couldnt have found that out much earlier in the episode.
Learning a little bit about Dons past life was interesting, with the Secret Service agent and himself forced to work together after a seemingly bad breakup that eneded because of Dons mother getting sick. Learning that Don was about to make a huge committment a couple of years ago really says a lot about him.
The one thing I dont like about this show is not following up on things they create in certain episode. In the episode before this one Charlie is about to ask Anita out before Don interupts. In this episode, Anita hardly makes an apperance and there is not further conenctions between the two. I hope this solution is solved in the next episode or two.
