I like your equation for Morgan But Sam is kinda Fish outta water in that one since she wasn't part of the MC's Childhood but Alexis and Sam kinda fits also Alexis and Morgan. All in all I agree with what you said
Well yeah that's fair Sam is in a weird spot. Maybe a scene with Her, Alexis, Sasha, and Bree would be better. You have your ex, Sam aka the best friends ex, and the two girls you came to love first in the game as well as the first harem you started. That fits better don't you think?
