Just a note, the teeming rules really meant for situations where the integrity of the game is compromised. Situations where innocence and traitors, with roles known to each other, are intentionally not attacking. If Kessler gave a knife to Panda? That would be some form of teaming. I would call that most likely moderate teaming, unless Panda then use that knowledge to affect the game in the future.
This isn't a compromise of the integrity of the game. While Kessler probably should have just killed Panda and defended his teammates, there is strategy in proving your innocence by not killing your teammates.
