Sam and Abby in “Gravity”

[to Abby, after her son Joe is injured and being sedated] I remember, when Alex was three... I took him to one of those bounce-houses at the carnival. Of course, he's in there with five and six-year-old kids, so he gets knocked down, right? And every time he tries to get up, he keeps getting knocked down- and he's crying, "Mommy, Mommy!" And- the attendant won't let me in because he thinks I'm some stupid teenager, right?

Abby

So, what'd you do?

I stood there, and I... cheered him on. And, every time he got knocked down, I told him, "I know you can get up!" But... that's when it hit me. They fall. And all you can do is be there... and hope they keep gettin' up.
