Set in Season 8, ep 13
It had been a few weeks since Eddie told Buck he was planning to move back to El paso, to be with his son, Christopher. Chris had left with his grandparents and moved to El paso last summer after getting mad at his father for finding him kissing a woman identical to Shannon, Chris's dead mother.
Buck, Eddie's best friend at the 118, wanted him to stay. He was struggling with the fact that he was gonna be gone. He was sabotaging all his showing of the house, and he had been doing some snooping on Eddie's phone when he wasn't looking. He eventually found you. You were one of Eddie's old friends from years ago, who still lived in El paso. He spent weeks talking with you and trying to convince you to come to LA and give Eddie reasons not to move back.
One day, when Buck was at Eddie's house, sabotaging the showing e was having, a knock was heard at the front door.
"Okay. The next possible tenant is here. You better not try anything with this one." Eddie warned sternly, fixing his hair before opening the front door.
"Hey-" he started, before he saw you at the door, he looked back at Buck, "What are they doing here? Buck- did you have something to do with this?" He asked his best friend exasperatdly, running a hand over his face.
