Nope. I found it too. It was a little bit weird....
For me it was weird for more than 1 reason.
The first because she seemed to be obsessed with MC, then she pops up like this...#1 weird
Her character never had some real purpose in the story, then when we are just waiting for the epilogue she appears like that #2 weird.
And i dont know how the epilogue is going to be, but if we stop to think MILF and her daughter didnt had a real purpose in the story either, MC had some story with them in the past, the game took a little while with them at the beginning...then they vanish just like Fiona, just appearing in some brief text messages conversations...i thought MC would travel to meet with them at some point before the end of the game.
Depending on the size of the epilogue the endings with them
if theres any can be a bit empty, because will be something like "oh yeah, theres so much time we dont see each other right?... lets make a future togheter and be happy forever....Yay"...,and i think theres a chance of the endings being more focused on Jaye, Mallory, Amanda and Lisa, and if we are lucky enough we can see a worth ending with Bianca and Tanaka.
