I also felt that scene was out of my DIK character... I presume DPC needed a sort of "shocking situation" to push the MC into Bella's/Sage's/Derek's paths... Personally, I would have preferred if this was the CHICK reaction only. My DIK reaction should have been exactly like Derek said: threesome. It's literally the first thing that came to my mind! The DIK MC proposes that, Maya and Josy refuse, the MC says "Screw you guys, I'm going home!" and he goes to Bella or Sage or Derek... I would have preferred to be rejected immediately, because being rejected at the end of episode 4, after Maya and Josy try to reconcile with the MC, it's a bit... I don't know. It's a bit schizoid and hurts even more.
I don't know. Does this possible DIK reaction make sense? Or is it stupid? It's not easy to make up a credible scene that could lead to the MC going to Bella's/Sage's/Derek's... Now that I try to imagine a possible alternate scene, I understand it wasn't easy for DPC either.
Maybe, rather than being a drama queen, I would have also preferred if the MC acted more mature: "OK girls, you clearly need some time to talk and clarify your feelings, I prefer to stay out of this, I'm going to search for another place to stay. No hurt feelings. Bye!" or something like that.
