Even when Soren looked back, Sephiroth appeared to have moved on, he wasn't watching the smaller boy as intently as he had been previously; his gaze somewhat up and away from where Soren was looking. At some strange formation in the clouds, it seemed.

He was just about ready to step away when he heard some bird-like call echo somewhere above them. At first he wasn't sure if it might be a trick caused by the altitude they were travelling at, or something completely unrelated but the second time the cry from the zu closing in came Sephiroth had no illusion that it was friendly.

"Heads up-" He called to Soren, who was still looking over the edge, as he unsheathed his sword and closed the two strides over towards the prow.
