For whatever reason, TNT decided to split the season in a very awkward place, with only one new episode (the one this week) before the season finale next week. The episode is in December, so I'm guessing "The Ho Ho Ho Job" was planned a while back.
"The Ho Ho Ho Job" takes a big turn with the return of Wil Wheaton's character, the computer hacker Chaos. The initial villain actually turns into a good guy in the end who regrets his actions. It turns out that Chaos was manipulating the team from the beginning to stage a bank robbery. After a bit of soul-searching by Nate, the team manages to turn the tables on Chaos and save Christmas.
Overall, the episode was a lot of fun with full usage of the Christmas theme. Elliot got to dress up as Santa, we got to see Parker's enthusiastic joy of everything Christmas, and the Christmas gifts at the end of the episode was really cool--and Sophie, presumably, gives Nate her real name.
Score: 8.8/10
