What I like the most about Zelenka is that he can get Rodney to listen to him when it's necessary. He's fully willing to tell Rodney that he's wrong about something and puts up with everything Rodney throws at him. Plus the muttering in Cezch is cool too. :O)

Lorne is great too. He needs to be given a canon first name though!! :O)

I have to agree with what someone else said about Kavanagh - I just wish the writers would give us some more information about him. If we are supposed to hate him they need to stop having the other characters overreacting to everything he does - it just makes the other characters look bad, not him.
