Grimmjow was definitely not a team player. He broke more rules than the other Espada combined. There was the Karakura Town incident which cost him his left arm. He later freed Orihime from captivity, just so she could heal the enemy. He then challenged Ulquiorra's authority, and finally released a Gran Rey Cero within Las Noches.

I may even have missed an infraction or two, but the irony is that the black sheep among the Espada, the one who had no concern for anyone but himself, managed to survive. Hallibel survived too and she cared a great deal for her Fraccion.

As for Grimmjow, there's a very good chance he'll return sometime this arc with a changed personality and start doing something good. He's supposed to be an ally now.
