start VN from scratch.
to be honest, the beginning is damn funny. At first, MC talks to his mother like a complete moron. At his age, he's 12! And he even pissed the bed. Well, the fact that he slept in the same bed with his mother is well known, incest does not happen without close physical contact, incest is a family matter, and family is sacred!
MC talks about himself and his mother in the third person, as if he were an idiot. Then, after a couple of orgasms, he suddenly evolves into a relatively consciously speaking boy. Miracles, and nothing more! Who came up with such a bright idea for a script move? Shyamalan was probably jealous.
Probably, an alien brain slug was involved here.
