This was one of my favorite episodes of the series. The way the entire sequence of events was woven together leading to the climax was excellent. The back and forth from the team's depositions to the guy in protective custody to the solving of the crime was perfect. Captain Raydor's support for the investigation and the way she managed to remain a part of it fit just right.
It's not about any one thing in this episode for me, it was one of those cases where the whole was definitely greater than the sum of the parts. Everything came together perfectly for a very enjoyable episode that needs to be watched more than once in order to pick up all the subtleties.
