Serena: I don't think I am going to do this. Blair would be crushed. If anyone is going to walk the runway in Eleanor's designs, it's her.
Poppy: Serena, I've only known you for a few weeks, but it's pretty clear you've spent your whole life worrying about Blair -- what she thinks and how she feels...
Serena: You don't understand.
Poppy: I was best friends for years with a girl who was just like Blair and it was subtle, but I was always trying to make myself less sparkly so she wouldn't feel insecure until I realized one day that it was crazy. A true friend would want you to be your beautiful, vibrant self.
Serena: I just... I really don't want to hurt her.
Poppy: I know, I know. But is that a good reason to hide your light? You're gorgeous, sweet, and amazing. If Blair's a true friend, she'll support you.
Serena: You're right.
Blair: Serena, can we talk?
Serena: About what? About how you tried to publicly humiliate me?
Blair: You know about the dress?
Serena: Yeah, Laurel told me. She said it was an accident. Clearly, she doesn't know you.
Blair: I'm sorry. I was hurt, okay? You blew off our most beloved tradition.
Serena: Just get over it, Blair.
Blair: Excuse me?
Serena: My whole life I have been bending over backwards to protect your feelings, and you know what? It's not my fault you're so insecure.
Blair: And I'm sure it's not your fault you're so conceited?
Serena: I'm just tired of trying to hold myself back so I don't outshine you.
Blair: Oh my God, can you hear the words coming out of your mouth?
Serena: It's just the truth. From now on, I'm going to be who I am, and if you can support that and not be threatened or competitive then great. If not...
