Derek cutting his finger off reminds me of SNL version of Good Will Hunting, lol. Just the same thing.
The new girl being Nick sister that would be the dumbest idea that DPC would add so far. We have been dealt with all girls dramas so far. It is time to have something fresh. If she would happen to be his sister, I wouldn't even care about her. The moment she tells me that, I tell her to f.. off. Even if things aren't Nick's fault, he even criticized the furniture that MC's dad brought to the mansion.
That is not other DIK's words, that is his words. Imagine your dad who isn't wealthy but is a hardworker, see that his son and friends are having a problem and try to help and then someone shit on your dad's help. The other things he said I don't even care, but this part specifically, he deserves no forgiveness, that just shows the kind of person he is. And with that I don't want any more interaction with him even if he come back and apologize. I can accept apologies, but I won't be friendly anymore.
And I wouldn't want any link to him either, I can find pussy anywhere. It is not like MC is lacking any.
