I was thinking about something earlier, and I thought, "There should be a Sierra, Gwen and Cody love triangle". It's just like the other ones, but different. It has a conflict: Sierra and Gwen, a friendship: Cody and Gwen, and two relationships: Sierra and Cody or Cody and Gwen. So if u think about it, Cody's the victim here. Let's just see in season 5. I heard that the new TD contestants and the old ones are gonna be together in that season. So, maybe Sierra and Cody will start a relationship, or Gwen will break up with Duncan and start a relationship with Cody. Who knows?
