When you're in a tricky negotiating situation, it pays to have someone else monitoring things and ready to pull an emergency pin to abort the negotiation and get you the heck out of there in a hurry. The person doing the negotiation is likely to be too distracted to notice imminent danger.
You can adapt this to roleplaying scenarios where someone is attempting diplomacy, or trying to calm down a potentially hostile attacker. Let one person do the talking, but everyone else should be on the lookout for trouble and able to get the talker out of there.

Wait, that's an engine? What's the point? There's already four engines, one on each of the wings! Is this meant to be a bolted-on extra hyperdrive modulator or something? There would hardly have been time to build anything if the First Order really did track the Resistance down that quickly! I had to go look, but that does look like a new addition.
Hmmm, Allan looks like he wasn't expecting the sudden acceleration. Perhaps in the movie that switch was to turn this thing on? That'd explain the visual focus on it. I don't think the movies had the requirement of pushing something to talk with other ships. Hyperspace jumping through the Dreadnought seems like it'd be a good way to die at the same time, so I guess this couldn't be the modulator from the last episode, as killing a main character off this early in the movie wouldn't make sense. At the same time though, then the question would be why would only Allan be out here with this thing if it wasn't a one-off device, especially if it's so important for the Resistance to escape?
General Hux: Enough of this! Fire on that fighter!
BB-8: I hit the engines and kick in the turbo!
Allan: What are you doing? I had them eating out of the palm of my hand!
BB-8: Like a one-armed zookeeper.
GM: The X-wing tears directly at the Fulminatrix at breakneck speed.
Allan: Hey, fine for you, you don’t have a neck!
Captain Peavey: He’s going for the dreadnought.
General Hux: Well, that’s some cheek.
Captain Peavey: <snicker>
