I'm not really sure when it takes place. Jerry in the movie is with the Trike and Ellie RIGHT before the storm. Whereas this scene is taking place when it is bright and sunny, and the storm occurs when Gerry and Jess are sleeping overnight in the bunker. Not really sure the events of the movie and the game line up right with Gerry Harding...
Everything would of needed to happen after the sick trike. Maybe he took Ellie back to the visistors center and picked up Jess. That makes sense right?
