Ryan Rottman is headed to Beverly Hills, and he's ready to fight for what's right!

The former Gigantic star and Greek/Victorious guest star will appear on multiple episodes of 90210 this fall as Shane, a young gay activist who is committed to marriage equality.

It's safe to assume Rottman's character will get involved with Teddy somehow, who may only be appearing in a handful of episodes, but who producer Patti Carr has said will be featured in a "great storyline."
