I see your point, the scenes are stronger and more emotional if you've been targeting all 3 (up until that point at least), the reveal of Alexis being Erynn's BFF(and that she knew you all along) and Layla's sister is much more impactful if you are in relationship with her.
"That's your sister? I've once sat on the plane next to her...", doesn't have nearly the same impact...
But the same appiles in reverse, if you aren't flirting/making out with Layla the reveal that they are sisters also doesn't hit nearly as hard.
With Erynn is less, since we can't be super deep with her at that point... but it helps if you at least like her a bit when they have their "fight".
it will be even funnier
when you are on the layla path but busted a nut on Alexxis!
MC - come on Layla, we can´t loose this flight!
MC - i am sure you will love alvarado, i am going to take you to all the places were i grew up!

Layla - whoaa, were did all that rage came from?

MC - i hope he would survive with those scars and in pain for the rest of his long useless life!
Layla - Babe, you are sort of scaring me!
