Mr. Goodman's car starts on its own, the crowd is quick to assume that Mr. Goodman is the intruder and blame him for the car starting.
Don't blame other's without evidence.
I...I know who the monster is!
Steve has a radio set in his basement and everyone suspects that he's communicating with the alien/monster.
Don't be so quick to blame.
Charlie shoots Van Horn and Van Horn falls to the ground dead.
Fear can lead to disastrous events.
Just sit back and watch the pattern.
Everyone starts blaming and yelling at Charlie because they think he's the alien/monster for killing Van Horn, but then Charlie says that tommy the kid is the alien/monster.
It's Tommy!
Ok then, tell us Charlie, tell us who the monster is!
He's just a kid!
What?
Everyone starts to blame each other and everything gets out of control.
No, it's Tommy!!
It's Charlie!! No, It's Steve!!
Car's don't start on their own. Les Goodman!!
Why are you being so quiet, Don!!
In the end, none of them were aliens, but they still thought they were aliens. The real aliens were up in the sky "watching the pattern."
