Frank has been known to get into a fight or 2. In fact, his relationship with Zach was far from perfect during the San Diego season, and even during the reunion they seem unable to reach common grounds.
If the San Diego team wants to finish together, Zach & Frank will have to be friends. From the looks of the previews, Frank will be getting in some fights this season. At the end of the day, his relationship with his teammates is what really matters.
Based on this video Frank and Zach seem to be embracing each other, and Speedos. In fact, the two attended the VMAs together last week and snapped photos as they got ready.
Perhaps they can work together? Is this the start of a new friendship?
