It's all about personal preference but I think this is a natural pairing for a side special like this game is. Theo and Ethan are like opposites in Justin's life but he can fall for either one. The original Christmas Special poked at the idea of the cross but this update gave us the real thing. And not only was it extremely well done (and hot af) but it exposed new sides of both characters without having to progress the primary New Hope storyline.
Long story short, I see a lot of appeal in Ethan x Theo.
