This scene made a lot of sense to me when I was looking for base of a
real relationship.
Since they aren't prepared well to prevent the alien attack and they
are force to take refuge in the basement of the house.
Yet the alien finds the way to get close to them through disused coal
chute and grabs Morgan.
Graham & Merrill do they best and drive away the alien but Morgan
suffers an asthma attack. Graham realizes that they left the inhaler upstairs.
Then, a worried father speaks to his son to calm him down.
He says “Don’t do this to me again. Not again. I hate you. I hate you!
The fear is feeding him. Don't be afraid of what's happening. Believe it's
going to pass. Believe it. Just wait. Don't be afraid. The air is coming.
Believe. We don't have to be afraid. It's about to pass. Here it comes. Don't
be afraid. Here comes the air. Don't be afraid, Morgan. Feel my chest. Breathe
with me. Together. The air is going in our lungs. Together, we’re the same.
We're the same."
