The Birkin Bag was Logan marking his territory like the fuckboi dog heād been for the agonizingly long entirety of his stay on the show. He might as well just placed a placard on Rory that stated she was his property because thatās what Rory was to him; property.
Thinking about that Birkin Bag again, and how Rory seemed actually kind of freaked out by the way everyone was fawning over it when she and Logan were out... And I think a big part of that is because she's used to gifts from a boyfriend being a kind of secret message between lovers that wouldn't mean anything to anyone else. But the Birkin Bag isn't just between Logan and her. It's to send a message to everyone ELSE too. It's not a sweet secret between the two of them, it's a Public Statement. Just like Logan's proposal was a Public Statement (and she didn't like that either).
