Linc saves a knocked-out Pete as a boat heads for the rescue. However, as the boat arrives you can see Pete take a gasp of air, reach out his hand to one of the rescuers and straighten his leg to get on board the vessel; something he wouldn't be able to do if he was unconscious.
Near the end when the Captain and Julie arrive at the dock, a reflection to the left of Julie is visible as she gets out of the car. Not only does the reflection move as the camera pans to the right, but the feet and bodies of the crew behind the camera can be seen in it.
