Now, you and I know she was about to bring up his baby mama, but he doesn't know that, which means this exchange has already happened, I would say, hundreds of times. This would be because Aria is incredibly needy and because Ezra is... at best, merely a boy. When Maggie knocks on the door, he assumes it's his neighbor who locks herself out once a week -- he even keeps a key by the door -- but what's really maddening about this scene is that somehow over the course of the next few seconds, it's going to go from "a thing that sometimes happens" to "a thing that was inevitable." Like, if he had just said, "It's Mrs. Rosenthal next door, she called and said she locked herself out again," it would make sense. But instead he just seems crazy and then clairvoyant when she does show up.

Maggie: "It's me, Maggie!"
Ezra: "Oh, balls. This is my girlfriend Aria. She's a little child."
Aria: "Ezra, I need to speak with you immediately. There's a chance if I come clean in the next one second you won't be pis..."
Maggie: "-- Nice to meet you, Aria."

They chat and catch up and whatever, they already talked on the phone but she was "in the neighborhood" so she just dropped by, which, if you think secretly not having the abortion was rude...

Maggie: "It's terrific that you're 'writing,' of course, but what made you give up teaching?"
Ezra, with an admittedly sexy-as-all-hell goofy glance at Aria: "Uh, it's complicated. Do I hear Mrs. Rosenthal?"

And it is Mrs. Rosenthal. And she has some kind of a Bundt cake happening.

Maggie: "Why didn't you tell him about Malcolm yet? What is wrong with you?"
Aria: "I know! And let's not even get into how creepy I am for lying to your face after stalking you at your job with your son standing right there."
Maggie: "Yeah, for some reason your obviously necessary apology for that never comes up in this scene."
Aria: "Anyway, are you going to tell him about Malcolm? I'd really like to be the one that does that. Since it's none of my business and all."
Maggie: "I still need to figure some shit out. Like how I can keep squeezing money out of that bitch Diane Fitzgerald."
Aria: "Sister, I heard you on that one. Fine, I'll do you the favor of covering my own ass."

Ezra: "...Whoooo wants cake?"

Ezra, none the wiser, then feeds Bundt cake to both of his high school girlfriends.
