Quote AbbieSue: He has to act that way, you see, because Dylan, "stole" Avery from him...it wasn't Avery's fault, she was just engaged to him, had a loyalty to him, still, not her fault, it's all Dylan's fault.
Avery is the one who, instead of going to get married, stayed and helped Dylan.....Dylan didn't even know it was her wedding day......still, in Nick's eyes, it's all on Dylan.
Then, he can't even see he's being played by Sharon, who, by the way, is using their daughter to get him back...THAT he is blind to.
Nikki should focus more on a relationship with Dylan and, let Nick twist in the wind, with psycho Sharon.
Nick is a self centered moron ,who is more like his father then he'd ever admit.He still has no clue what his lie did to Summer and has this stunned expression whenever it's mentioned.He excused himself by saying it was because of Cassie's death and has no real guilt.What Nikki did to Dylan is much the same thing.Everything he believed about himself and his parents is a lie.Of course Nick never thinks about how this affects Dylan,it's all about him and his own selfish feelings.He needs to grow up and get over himself.If Avery really wanted him they'd still be together,it's not Dylan's fault.
