you remember that episode of Dexter where he drugged his girlfriend's ex-junkie ex-husband and then his girlfriend was like "how did you know the exact amount to drug him with? are you a junker? you need to go to NA meetings!"? why didn't he just say "i'm an autistic cop, i know weird science shit?"

dude spent his entire life learning to lie about what he was doing when he was committing heinous acts of murder and desecration but couldn't figure out a lie better than "uhhh yeah! that's right babygirl! i do heroin!"
