The car is not starting too. It doesn't make sense.
He must be one of them
I don't understand. What's happening?
How come his car started all by itself?
Why didn't he come out with the rest of us?
Oh, now you're suspecting me?
Who do you talk to on that radio, Steve!
Steve, please! It's just a radio.
Person vs. technology conflict: The neighbors become frightened when nothing works.
You killed him, Charlie. You shot him dead!
You killed Pete! And the lights just went on in your house too!
I didn't know It's him! I don't know why the lights are on! I swear!
Person vs. Society conflict: The mob interrogates Les Goodman because his car started by itself and think that he's one of the aliens.
It's not me, I swear! It's...It's the kid. It's Tommy! He's the one.
He knew. He was the only one who knew! He told us all about it!
How could he have known? Make him answer.
He's only a kid!
Person vs. person conflict: Charlie accuses Steve of communicating with aliens.
What about Les? His lights turned on too!
Pete may have had information for us. That's why he killed him!
It must be Charlie!
Person vs. Supernatural conflict: Carlie shoots Pete, thinking he was a monster. The aliens are manipulating the neighbors to blame Charlie.
It's Pete Van Horn!
Person vs. Society conflict: Charlie accuses Tommy of being one of the aliens just to find a scapegoat. The neighbors start accusing him too
The residents of Maple Street are confused, scared, unnerved, and don't know who to blame. So they all accuse one another just so they can find a scapegoat. Or in other words they argue and bicker over who they think is the alien.
