It’s interesting how some things work better in different mediums. In the movie, I dislike this scene; it’s not the right time to make a goofball joke that goes on for as long as it does, and it hampers the scene overall. I was prepared to cut it from the book, but reading it in a novel, I actually thought it was unobtrusive and much funnier than its movie counterpart. (This is my edited version, by the way; I still did some minor trimming and restructuring.)

They turned a corner and came face-to-face with another pair of patrol troopers, who raised their rifles.
“Drop your weapons!” one ordered.
Finn didn’t want to kill anyone else. Besides which, leaving a trail of bodies throughout the ship would just make it all the harder to rescue Chewie and escape. But if he had no choice… he went to raise his blaster, when Rey spoke.
“It’s okay that we’re here,” she said, calmly but firmly.
Finn held his breath.
“It’s okay that you’re here,” the stormtrooper echoed.
The other trooper nodded.
“It’s good,” he added.
“You’re relieved that we’re here,” Rey continued.
“Thank goodness you’re here!” said the first trooper, his shoulders going slack.
Poe leaned over and whispered in Finn’s ear: “Does she do that to us?”
Of course not, thought Finn. She’d never – no, wait… she definitely had. To keep him from following her into the desert and getting run down by Kylo Ren’s TIE fighter.
Oh, hell.
“We’re looking for a prisoner,” Rey said.
The stormtroopers gave directions to the cellblock where Chewie was being held, then resumed their patrol as Finn and his friends raced away. Within moments, they came to a split in the corridor, just like the troopers had described.
