Obi-Wan's still coasting through the situation fluidly, completely in-tune with the Force now. He can sense where everyone is and exactly how tense they are:

Jade's anger is a mirror to Anakin's more contained irritation; Kista is all bluster and indignation, which puts her as the most likely to run her mouth off and make things worse.

The trio of guards are each a ball of nervous energy, which pegs them as easily dispatched, yet at high risk of accidentally shooting someone.

The only true threat in the room in Malco. He belies nothing of his emotions, and Obi-Wan has to admire that. Unfortunately it means that Malco has been calling the shots - pardon the pun - with this strange refugee operation for far longer than Jade and Kista probably realize.

Only one plan really presents itself: A simultaneous gesture from Obi-Wan to topple Jade's chair while pulling Malco's gun into the Jedi's hand and shooting the man in the leg would take care of those two problems. The speed of the maneuver should serve to keep the guards blinking stupidly for the half a second it would take for Obi-Wan to then turn and dispatch one, possibly two of the guards before turning the gun back on Malco.

As for Anakin, his responsibility would be protecting Kista and whatever remained of the guards.
