I thought it was a very good episode, Lindsay is going to be a great addition to the cast, but there are two small things dat I want to bring up:
1. It would be bettter if they showed something of the thieves from the beginning. I assumed it were thieves, since the security guard was chasing them and they had a bag.
2. I think it's really crappy they didn't mention Aiden. Looks like the same they did with Speedle. Even Danny didn't mention her. In NCIS, when Kate was replaced for Ziva, Abbey was a bit bitchy to her and the others weren't that open too. I missed that with Danny.
EDIT: I thought the shots of the animals, especially the tiger of course, were very beautiful.
