Nick has always been a quiet DIK, mostly crying about Vinnie or just being awkward. I wonder why his clown face got to feature on the Episode 9 banner, he only spoke 7 lines in the whole episode...
It's simple. In the animation where the Pink Girls come to the party, we see Heather talking to Nick in the kitchen. In EP7, Tommy told Nick not to screw up again or something like that. Nick replied to that so it was an honest mistake. We know from Rusty so Nick doesn't have the best tact. Who knows what Nick advised Heather to do in this conversation.
I only know one thing, the MC states so Heather is out for revenge and wants to use the MC to do it. Why? Tommy is already pissed off by the MC anyway because he does everything better than him.
But there is one question I ask myself. Where can Maya suddenly shove the MC's tail down her throat? Did she practice with a dildo.
I think so that Maya and Josy have already been around a competition for the MC. Maya has seen in EP8 how Josy teased the MC with the banana. Maya may have been practicing something with a dildo.
Josy mentions something in EP9 "Chickenrace" and that she will not be the Chicken. The two were probably egging each other on as to which one the MC liked better.
