I salute this awesome community!
After about a year of lurking around here I write my first post to express how much reading all of the discussions and theories has enriched my enjoyment of the game and expanded my entertainment.
And now my contribution to get a discussion going.
It is implied more than one time that Neil may not be the MC's biological father (family isn't defined by blood, Fuckface doesn't look like Neil etc). Of course these clues could be red herrings DPC style, but they could also be foreshadowing. If the latter is the case, Fuckface could read in Lynnette's diary that she discovered she was pregnant and hooked up with Neil to make him take responsibility for the kid, either with or without his knowledge. Then we have good old soapy drama.
Does Neil know? Why hasn't he said anything when the MC got older? If he doesn't know do we tell him?
And most important of all: Who is PapaFuckface???
What do you think brothers (and/or sisters)?
I think the fact that Neil is not the biological father is 70% proven. The characters emphasize several times that Tremolo does not look like his own father, the relationship between Lynette and Neil is similar to friendly, but not romantic. On the other hand, I do not know how DPC can show this without hurting the feelings of the ANTI-NTR Guard. Lynette is too young and clearly doesn't have a romantic partner. Perhaps at some point, MС leafing through the diary finds out that his mother is pregnant, although his father and Lynette have not even started dating yet. Her boyfriend was a rich jerk who immediately left her, and Neil, as a good guy, promises to raise someone else's son as his own.
It would certainly be a good drama if it turns out that Rusty and Tremolo have the same father, for example. They would become brothers not only by brotherhood, but also by blood. It would be beautiful.
Tommy is only Josie's half-brother, this is clearly done for a reason, so Tommy can also be MC's own brother.
And now back to that meeting......
