Key supposed that he shouldn't chuckle at Priscilla's trepidation, but it made her so cute that he only just managed to bite back the laugh. "Yes, that's the one that we're getting on. Come on and be careful of the other people and like...don't fall onto the tracks," he added with another chuckle. It wasn't really possible to have an accident getting onto a train, but it still paid to be mindful, especially of getting shoved by rude passengers. Thankfully, it seemed like more people were getting off than on so Key held back to wait for all those exiting, all the while holding Priscilla's hand. Which was warm, and kind of amazing of a feeling if he thought about it. Once it was clear to get on, he tugged Priscilla toward the least crowded car he could see.
