a level 3 PC threw a bomb where the AoE knocked an ally of the party (PC) unconcious. The ally (lvl 1)wanted his animal companion to attack the PC who threw the bomb.
The level 1 is obviously a consenting member into PvP.
Does damaging/and knocking unconcious an allied party member constitute as consent for PvP against the ally's animal companion? Or, does the PC lose control of the animal companion, and the GM makes the animal companion behave accordingly?
Neither action was actually taken, and the GM ruled that according to the current PvP rules no action like that could be taken?
Looking for consensus in the event that situations of such occur in the future.
Obviously using the AoE to hurt your PC wasn't the intention. It was an unfortunate side effect of hitting the thing attached to you, which is the problem of having a small creature attached to a player occupying the same space which is unlike a grapple where the opposing creature would merely hold you in place instead of becoming one with your square. The situation would not have even been a problem or issue if not for the strange custom ability that was made for those encounters.
It does not mean that your character should get to avoid the negative consequences of intentionally endangering another PC. The likely consequence of this situation should be that the animal companion turns to take vengeance on the individual whom threatened his master, especially since the PC is unconscious and would not be able to stop him.
