1. "We're gonna be OK."
"The Car," Season 2, Episode 15
Every moment of "The Car" could fit somewhere on this list, but we kept it to only two spots just to be fair. The episode cleans up the mess of Jack's death, allowing the audience a full-on spectacle of grief to help process our devastation. It isn't an easy watch. Every moment with Jack is an arrow to the heart, and every moment without him even worse. The family car is a framing device. Jack buys it to protect his family; what he doesn't know is how it will care for them even after he's gone. We see an array of family moments in the car, both happy and sad: a joyful singalong on the way to a Weird Al concert; an angry fight between brothers; Rebecca driving her kid's to their dad's funeral, trying to ignore her dead husband's coffee in the cup holder.
The final montage of the episode ties all of those moments together, in one cathartic, tear-inducing swell of emotion. Rebecca gathers the kids at Jack's favorite tree after his funeral and shows her maternal strength. She insists that Kevin and Randall don't have to take Jack's spot, and that it wasn't Kate's fault her dad went back for the dog. They spread his ashes, and head off, but Rebecca lingers for a moment. "We're gonna be OK, babe," she whispers. "I promise you, we're gonna be OK." It's a quiet pledge -- to Jack, to us -- that though we move on, we never lose sight of the things we've loved and lost.
