STUCK! no dives along with a kid. (The Last Guardian)

In General stuck can't dive with a leotard for some reason he dives 1 and when I'm on the neck is not! already 40 minutes trying to dive in! Passage watching all did, and Kaplanova dives I have, with the control points already I go as well. this is a bug? all enough? press R1 and the cross around his neck.
