Grace finally decides to break up with her long term boyfriend Danny, but she receives an unexpected proposal of marriage from him which she says yes to.
When Grace goes to see Will to ask for his blessing on their marriage, Will attempts to be supportive of his best friend's decision, but it isn't long before he tells her that Danny "isn't enough for you". This puts her in an awkward position, telling Will that she doesn't need his blessing and she's going to go ahead with it anyway.
Will shows up at Grace Adler Designs the following day with the intention of apologising to Grace, but she has gone to City Hall to get married. When Grace shows up, it turns out that she has left Danny at the Altar, realising that Will was right. Will reassures Grace that Danny was only "A plot point in my movie" and she has to keep going if she wants to have a happy ending.
