Gavin directed the 7th season of Red vs. Blue and was then hired full time. He actually started The Slow Mo Guys so that he could get his work visa. He's now the Creative Director of Rooster Teeth.

If anything, she's got a much more sadistic sense of humor than him.

Considering that Rooster Teeth has continued to expand beyond just video games, I'm sure that he'll be able to find something to do. Not to mention that he's got a voice acting career outside of Rooster Teeth, so he's got plenty of opportunities.
