Hahaha, it all boils down to one's playthroughs for fairness.
In my playthrough Sophia doesn't even get to meet Tyler, Ellie is definitely not with Logan, nor with Julia and least of all Lesbian, nor with Sophia. Sophia is all focused on her son that no one else gets to approach her in that way and if she is forced to it's because to protect him until finding a solution, even less her old-time friend and neighbor's son. It's more of a Mother & Son story that they've had all the kissing (even when it was a peck...as of yet) the flashing, the rubbing, massaging, modeling, photographing, tickling, breakfasting and changing together, and the wanking...and as the song says, "The best is yet to come"
