It's not a big thing. Just a kid dived too deeply, got trapped under the dock and freaked out, trying to find his way up. Ezra follows the feel of his fear, finds him just at the edge of the dock and pulls him out, pushing him to the surface.

Spot may see the kid breaking water, crying out, and his friends splashing over as they realise he's in trouble, checking he's okay and pulling him out.

Ezra surfaces a shot distance away, watches the fuss for a few seconds, then pulls himself out of the water again.
