Gloria and Manny arrive at Claire's. As the three of them talk, Alex comes in to see if Claire approves of her clothes.

As Mitchell and Cameron are looking for stuff at Costco, Mitchell finds the shredder that he always wanted. Amazed at this, Mitchell looks at the store as something wonderful instead of being snobby about it.
Gloria takes Alex to a restaurant and has a talk with her. She tells Alex that she can talk to her about anything, to which Alex starts asking her very personal questions.
As Jay is flying his model plane, Phil tries to make small talk with him. After awhile, Jay tries to get him to stop by telling Phil to help him with an airplane maneuver.

As Gloria reveals more about herself to Alex, she asks her why that she doesn't want to wear a dress. Alex tells her that she doesn't think that she is pretty like Haley. Gloria tells her that she is very pretty and that a busboy was looking at her. Gloria tells her that she'll want to date a cute boy like that, and that she'll then want to wear a dress.
Gloria and Alex returns to Claire and Manny, and then Jay helps carry an injured Phil inside. Claire is mad at Jay because he hurt him on purpose and that he has never once said that he liked him.
