It’s very hard to defend Lorelai in this episode. Although she was clearly blindsided by the news about Rory applying to Yale, and it must have stung to find this out along with strangers and bare acquaintances, she behaves horribly by throwing a very public tantrum at her parents’ dinner table in front of guests – and at Thanksgiving, no less.
She’s thirty-four, but once again, behaves like a petulant teenager, and also tosses around some false accusations that Rory has somehow been brainwashed into applying to Yale. This comes across as paranoid, and is pretty insulting to her daughter – she’s eighteen, and capable of making her own decisions.
