Zoey most probably has an affinity right? Like MC. That's why she gets to choose between dik and chick choices. My question is how many dik or chick points does she need to get dik and chick affinity respectively? And what changes can we see in her behavior episode 9 onwards depending on her affinity? Does she have a neutral affinity too?
Once you played the interlude once, you can skip it, the only choice it gives you is if she takes the phone. If she does, she acts like a Dik, if she doesn't, she acts like a normal person, so i'm guessing the rest is window dressing
So i've looked at the Interlude code, the responses give Dik or remove Dik points, if by the end of the interlude Zoey has more than 0 points, it flags a variable called zoey_dik.
The 2nd part of your question, there's not a lot so far. If Zoe is a Dik, she swears a bit more,
shouts at Tommy if he moans about the party
If she's not a Dik, then she'll be a more polite,
admonish Tremolo for punching Oscar, but 80% of the dialogue is the same.
