When re-watching Jurassic Park (1993), I felt a bit awkward at the security room scene. While Lexi was trying to reboot the system, Alan and Ellen were trying to keep the door closed due to a velociraptor trying to break in. They have a loaded shotgun, but it is a little too far for them to grab. Alan and Ellen are keeping the door closed, Lexi is trying to fix the security system, and Tim...is just hitting Lexi's chair? I had been very curious why didn't Tim just pick up the gun, he literally was doing nothing.
Note: When I mention picking it up, he did not have to use the gun, but at least hand or kick it over to one of the adults, so they can kill the velociraptor.
