Seeing as Gallagher already has a high Force pool and bonuses to Living Force rolls from Charisma and Awareness, I'm okay with that!
Gallagher will interrupt the argument they are having with Denzral, and subtly wave his hand while speaking.
"You will allow me and my friends to pass," Gallagher says. "We are no threat to you and it's okay to let us through."
(Well, my first thought was to rush in, blades lit, and tell them it's over. But that might incite something we don't want. Maybe just walk in like we own the place, ala Windu and company when they tried to arrest Palpatine. (Hope not a true analogy in the end). We let them know we here, who are are, and what's going to happen next. Assuming there's not a fight, we kick them off the ship.)
