While Tom is talking to Weaver, Hal looks up at the moon. The moon that is shown is not the actual face of our moon.
While Ben and Kadar are talking about Lexi's aging problem, you can see a man with a ponytail, yellow shirt and tan vest with a girl wearing a pink flower shirt and apron. When Kadar says "But when she stopped that mech...", both Kadar and Ben turn to look at the mech and the camera shifts to the mech where we see a familiar duo walking past it, but when the camera shifts back to Ben and Kadar, Pony-boy and Flower girl are still there also, even though Ben is still looking at the mech.
