Right. As the person who was playing AI for the wrestle-ops round, and got to watch what happened while reporting things to security... Nuke ops showed up, shouting on comms about their wrestling matches. At some point, while I was bouncing around checking on everyone, I noticed one of the nukeops and Ivanova were engaged in a push-war, which I was under the impression was a consented wrestling match - Nobody was harmed on sensors so I made a note of it and moved on. I came back later when sec radio said Ivanova was dead, to find one of the ops had decapitated Jun, and Hypatia was trying to subdue them on her own.
I wasn't monitoring this non-stop, but the tidbits I did see, it looked like Hypatia hadn't actually started fighting until after they'd already killed Ivanova.
