Because S2 doesn't take into consideration S1 point/paths, as far as I'm aware the only relationship you can setup for Theo at the start of S2 is for his relationship with Megan.
And to answer the folks who say it's normal for Sue to shag Theo rather than her son (if one uses the patch), is not THAT obvious if one applies non-AVN logics, the same logic applied to say "she doesn;t want to shag her son"
Why would a mother, whose son has confessed his love for her, who has already had sex once with said son, who's understandably panicked... comes back after disappearing, listens to her son confess again his love for her and the very first time her son's best friend is at their place.... shag him?
Also please note, not everyone plays with mods installed, and while the choices in S1 were relatively self explanatory, that's not the same in S2
EDIT: I mean

Sure the bottom ones are clearly the more negative, but except for the last on the right (do whatever you want), what tells you which one might lead to NTS/NTR?
"Great more melodrama" - "Ok then I'll shag your best friend, son!"?
"Maybe I'm a fool." - "Oh you don't even know how big of a fool you are son!"?
