If Rodney McKay has to have someone other then himself do something, it would be this man. Dr. Zelenka has managed to show he is a top notch scientist himself, and while he doesn’t get everything as quickly as McKay, he can get the job done. The two scientists have a sort of bond between them, although the constant jabs and bickering would tell someone otherwise. Zelenka has definitely earned a place in the Atlantis team's heart.
