I heard that Arbitrator, his copy and Zenyatta were in the same room together and things got heated. The copy got punched in the face but Zenny moved between them and everything. It was actually like something out of a holo, it was so intense

I personally think they were fighting over his affections. Like Arbitrator got jealous, and knew that he should make a move before his much nicer copy sweeps him away. Anyone else think love triangle?
