It doesn't help that the nightmare around them wants Locus to catch her. Somehow, it seems to assist when he clambers up after her, boosting him one small movement at a time, until he goes silent.

She can run, but there's no more outward sign of him being there, or being in pursuit. There's the soft clicking that says he's there somewhere, but it echoes. It could be coming from anywhere.

He will not outrun her. He needs to surprise her before attempting again.
