I'd not respond well to Clarke/Echo scenes, but if they work together as far as like, solving problems or in group scenes, then... maybe. I didn't respond well at all in 5x12, and I can't see myself enjoying them any time soon.
I think it would feel very forced and unnatural (IMO). I do understand why you'd like that, though, Becks. I think my response would be the nature of the scene (context and also what they talk about).
Clarke/Gina would have been so cute, honestly. I wish they had a scene at least. Or that we got more of Gina. Oh well, that's what fanfic is for.
