"Bubbles, why would we need to jump ten feet? We can just climb the wall itself - or do you think we've forgotten the way you scaled the Peddlefoot barn on a dare? You raced Jyn to the top, too - just."
"I agree that a longer rope might be useful, although I am very loathe to turn back now. The thing is - any time we have a drop we can't climb, we're going to have to leave our rope behind. That could turn into a lot of ropes. And besides - are we going to turn back at every perceived obstacle? We won't get anywhere if we do."
"I think we're making too much of this - let's at least give it a try."
Having said this, Alton leans back and steps off, descending the rope at a steady pace. As he does so, he realizes that he can brace himself against the rock wall at his back to give added stability. He calls up his discovery to the others then concentrates on his descent.
