1. Enver Gjokaj who plays Victor is amazing. In The Left Hand, Victor gets imprinted as Topher so there are 2 Tophers working on the case. Gjokaj does a spot on imitation of Topher. In previous episodes he does a great job playing Kiki the airhead student, Terry the serial kidnapper, and Dominic the former head of security. Gjokaj should have quite the career after Dollhouse.
2. The 2 episodes are just packed with action, revelations about the reach of Rossum Corp and the mythology of the Dollhouses.
3. We get Summer Glau! Her character Bennett and Topher together were so cute.
4. We get 2 Tophers, which was fun.
5. Maurissa Tanchareon shows up.
6. Alexis Denisof does a great job as Daniel Perrin. I just finished Angel season 3 where he plays Wesley. Gotta say, I'm liking Wesley more and more as he gets more bad ass. While we're on the subject of Angel Season 3, I gotta say, what is up with that ending? Cordelia ascends to a higher plane? What? And Holtz played a deep, deep game. Looking forward to seeing how Season 4 starts.
All in all, I agree with other reviewers that these 2 episodes were very good and I look forward to the next episode and the series ending on a high note.
