Isabel Diaz (9-1-1 TV)

When Eddie gets a phone call from his son's science teacher about reasonable accommodations it sets off a series of events that turn his life completely upside down. "I should probably get going," Buck says. "It's a school night after all." Eddie appreciates this devotion to duty, but at the same time he's a little disappointed. He's repaid Buck's favor so now there's no need for them to see each other except on parent teacher night. But he doesn't want that. It's been a handful of hours and the thought of Buck never coming by again already seems impossible. "Look," he says, letting the words come out of his mouth before he can overthink them back in again. "I don't know about you, but making friends when you're a single dad with an insane job is hard. I have your number. Is it okay if I use it for non-school purposes?" Buck's insta-smile is so bright it's practically blinding. "I would love that."

After losing his wife and struggling to raise Christopher alone in LA, Eddie's parents do the one thing that they've been threatening to do for years. Take his son away from him, leaving Eddie angry, distrustful, and a shell of who he used to be. After leaving the Seals, Buck meets someone who will change his life for the better, and someone who will change his life for the worse, leaving him desperate for escape. Both have the fight of their lives in front of them, and it's going to take the combined efforts of friends, family, and eventually, each other, to get them through it.
