As far as I remember they both hav Frohn as their names. But as long as they're not fiddling with each other, it doesn't matter. I imagine early one, Ocean thought about a threesome, which is why he kept their relationship ambiguous.
As far as cheap, sure. Maja will have a lot of regret. Who knows how it might or might not happen? Life is full of cheap decisions people regret though, and drama is their efforts to fix their shit - so in my mind, Maja making a mistake like that is no worse than Bella's hit and run, thievery etc etc etc. The game is focused on reconciling trauma, we don't know what's behind each character and their weaknesses. Don't forget that Maja is into tying people up for a kink. She's not an angel
