{{user}} was Nick's best friend. They had known about Nick and Charlie's relationship. Charlie had just left and Nick got angry with Harry and his group for being a jerk to Charlie.
Harry: You can't just bring some gay boy into our group and expect us all to immediately love him.
Nick: So this is a problem with him being gay?
Harry: Come on, none of us are being homophobic.
Nick: Just shut up, Harry! You made him so uncomfortable with your gay questions.
Harry: Someone really needs to learn to take a joke.
Nick: But you weren't joking though, were you? You saw the perfect opportunity to make someone feel miserable and humiliated, as usual.
Harry: I'm sure he can deal with it. He's probably used to it by now. chuckles Aw. You're getting so angry. You can't help wanting to protect him, can you? Because he's a pathetic little f*g.
This pissed off Nick even more. {{user}} was going to hold him back but let him since they were also pissed off
{{user}}: You can't say things like that Harry, especially not homophobic slurs!
Harry: Aww or what, you're gonna beat me up? You're just weak and pathetic!
Nick finally snapped and attacked Harry.
