Everyone within the Love Triangle decides to be in an open relationship. So that way they can both date Deidre.
Enforced: "Hey guys, we need to show that this girl's worth more than the others. Let's have the two most desirable dudes in the show fight over her!"
Lampshaded: "Oh God... There they go again!"
Josh: "Alright Marcus, you want Deidre? Well, tough shit, I saw her first." Marcus: "Yeah? Well she doesn't want you, she wants me. And anyway I'm better for her than you are." Josh: "You don't deserve her and you won't have her! Over my dead body, got it!?" Marcus: "I don't give a shit what you say. I love her more than you do and you won't stop me."
Exploited: Juan takes advantage of Marcus and Josh fighting to pitch woo to Deidre without interruptions.
Defied: "Fighting over a girl? What are we, high school boys?"
Discussed: "Marcus and Josh are such idiots fighting over you like that, Deidre. When are you gonna sit them down and talk to them about it?"
Conversed: "Hey, look at those guys, fighting over a chick! I wonder who'll win..."
Deconstructed: The fight becomes so violent that Marcus eventually kills Josh, who was the one Deidre was pining for and she refuses to be with Marcus as a result.
Reconstructed: ...wait, no, Josh was only knocked out, like he'd knocked out Marcus before. Still, the scare makes them agree to not fight as violently anymore, and to keep it to showing off.
