At which point she realizes she just totally called him Ezra, and the whole room just heard it, and everybody feels super weird because for half of them, poor Aria, but for the PLLs and maybe some other insightful people (maybe A is IN THE ROOM!) it's a whole other problem. Any other episode I would question Aria here, like maybe this is the Freudian slip where everybody knows that she wins because she's with Ezra, but I think it's really just so everybody can stare around all mysterious like always.
Emily takes the French book over to Toby's and he wonders why Spencer didn't bring it and, in her sweet Emily way, she explains that she would not have taken No for an answer because she wanted to clear the air about the... Oh that's right, I remember: Jenna turned him in, so he'd be stuck forevermore in her house of horrors and the porch of perversion. (Which makes her excitement about getting his anklet removed, after he turned her down forevermore and she slapped him, sad and possibly double-weird. Or sloppy writing.) Toby apologizes back for being cagey about it the first time, and she asks him to have a celebration date, just as friends, for breakfast tomorrow.
Byron comes to pick up blushing Ezra up for their date, and he is being intense about it: "My daughter thinks that you are pretty hot stuff, and you know what? After reading your stories that Aria gave me, I have to agree... Very bold of you, exposing yourself to your students." Ezra giggles like a schoolgirl, and that's that, they go on their date: Schoolgirls are like the number one thing they have in common besides tweed jackets, elbow pads, Pavlovian salivation at the word "tenure," that gross academic smarmy superiority, and the whole frustrated-writer thing. Oh, and Ella.
So they have their beer and somehow Byron convinces Ezra that his relationship with Aria is a lie because she's looking at colleges in California and eventually she'll leave, they always leave, because we keep getting older but the schoolgirls are always the same age. So now Ezra's thinking he better dump Aria before she dumps him, or gets him fired and thrown in jail for a shanking or worse, or something. Mostly he just stares at Byron like, "I would totally thank you in my Oscar speech, Tiger."
