Question: In the altered timeline, Flash initially could not travel through time because there was another speedster. How was he able to travel through time in the original timeline, when Zoom was alive there as well?
Answer: Flash couldn't travel through time later in the movie not because Zoom was alive but because Zoom was also tapping into the Speed Force, preventing Flash from gathering enough of the Speed Force to break the Time Barrier. When Flash originally went back in time it's likely because Zoom was in custody, therefore not tapping into the Speed Force at that time.
Answer: Batman kills Zoom so the Flash could use the speed force.
Question: Mike and Sulley are able to activate the door when stuck at the kids camp by harnessing enough screams to activate it. If laughter is 10 times more powerful than screams, then why wouldn't child laughter (especially if there is a Birthday party, etc.) not activate doors from the "human world" allowing kids to go into the factory (monster world) all the time?
Answer: Well a door first needs to be activated from the monster side. See the doors of the human world lack the receiver for the energy they need to open the doorway between worlds (the red light on top). That's why in the monster world they hook a door up to a machine to activate it allowing the passage between worlds before any scream or laugh is made. It costs power to activate a door to allow a monster in. Boo was able to activate doors because she was in the monster world and her screams and laughs triggered the devices on top of the doors, activating them automatically. This was the first time ever a human entered the monster world.
Question: If Grug is so scared of things in the outside world and considers anything new to be dangerous, then why does he keep Guy with him instead of getting rid of him?
Question: When they look at the map showing the route to the time machine, is the line a different color than the line they actually follow to get to the time machine? (My 11 yr old son thinks it was blue and then they followed the red line).
Answer: There are two lines on the map. The red line leads to the time machine and the blue line leads to freedom. Reggie refused to go on an adventure and just wanted to spend his freedom eating pizza and watching TV, so when looking for the way out, he told Jake that the blue line was the way to the time machine in hopes of escaping. Unfortunately, because they were chased by government agents, they ended up following the red line and finding the time machine.
Chosen answer: The car is always shown in shots from the front so we can't see if the boot had a leak.

If the boot had a leak large enough to admit the starfish it would have filled with water and Gru would have drowned.
