The tiniest of smirks found its way to Kylo Ren's face as she asked if all she had to do was hang on. "Of course," was his simple reply before looking down and moving himself forward on the bike to allow her as much seat as possible. Another tick mark of insanity, he supposed, for doing something he was certain he would never have done before this island.
Somewhere, in all of that darkness slowly being pushed out by the tiny flicker of light, he had a passing thought it was a good thing he'd been put here.
"When we turn, you'll need to lean into it with me," Kylo Ren said as he held out a hand for her to come forth. "Otherwise, we will likely crash." There was just enough seat for her to share, though most of her rear would probably end up on the metal portion of the bike. All in all the dip for the seat wasn't so great that it would make much difference save in comfort.
