Hey now, Lyall really isn't hard to keep up with. He still has a biology teacher's physique, after all, so he wasn't going all that fast. And now, in fact, he's going even more slowly. Walking silently isn't exactly a thing he has practiced, but he's trying. It doesn't help that he has to hiss at Toushirou at least once, "Slow down. Don't get ahead of us."

The stairs creak a bit as he climbs, but otherwise the trio isn't particularly loud, and Lyall turns off the staircase in Toushirou's wake and into the hall Proud turned down last, moving cautiously, fully expecting to see the man in it, or in a room off said hall.
