A/N: Written after 3x13. The wedding cake line gave me a lot of feelings.
Spencer taps a fork against her glass, the clinking sound disturbing the chatter and laughter in the room. She stands up and everyone's attention is on her. Well, maybe not Paige's and Emily's, because they're lost in each other, but she's sure they're going to listen.
She clears her throat and looks around the room, until her eyes settle on Emily. "I'd like to make a toast." She sees Emily whispering something into Paige's ear while she takes her hand and then they both turn towards her with wide smiles. Spencer is pretty sure she hears Aria say 'Aww, look at them.' and she feels her own smile growing.
"On Halloween a few years ago, a lot of things happened. Most of them are nothing I want to talk about. But there is one thing I remembered earlier today when I saw Emily in her dress; when we saw you two walking into the room, it was the first time we really saw you as a couple and I remember Hanna saying 'They look like a wedding cake from outer space.'"
Laughter rumbles through the room and Hanna shouts "They did!" Spencer laughs at that and nods. "She's right, you did. But what I wanted to say is: we should have known then and there that the two of you were going to make it. That one day we would be at your wedding, that you would get through everything together. And you did." She raises her glass in Paige's and Emily's direction.
"Today, we are at your wedding. I don't think I need to say something like 'May their love last forever', because everyone can see that it will. So, to you, Emily and Paige!" Taking a sip, she sits down again, setting her glass on the table to look at the couple.
The smiles on their faces could light up at least half of New York and just as they're about to get lost in each other again, Paige turns her head towards Spencer and mouths 'Thank you', before turning back to Emily, who sends Spencer a wide smile.
She smiles back and looks at them a little longer. Yeah, she should have known.
