According to the ending choices, there is a harem route with the MC and the three women. I'm guessing, at that point, Bob is already gone or is in complete oblivion about the whole thing. I'm guessing maybe ICSTOR combines storylines, especially when it comes to Bob, his business & the twins wanting insider secrets.
Like you said, the MC probably takes over and they all go crazy for him all the time, just like the harem ending in Faerin's MotH
I have three saves for Linda:
Save 1 - No blanket & No Twins
Save 2 - No blanket & Helping Twins
Save 3 - Blanket & No Twins
Just because I don't know if helping the twins bleeds into Linda's storyline or not, since it is technically a different route
