Going down is easier than going up, but she's already decided she'll be taking the stairs. She's behind enough to not need to pause when Ezio struggles with the window. The climb is still less anxiety-inducing than whatever might be in the room.

Either way, she has a feeling they're not going to have much in the way of answers. When did they ever, here?

Grunting, she follows Ezio to the window and holds out a hand to be helped in. No shame in that.
