Do you lot remember the prop store selling the costumes and various props from the movie? Yes? Well, do you remember how one of the props was a data pad thing from the Academy?
I, uh... actually took the time to look at it closely. And, assuming I read it correctly... today (December 12) is River's birthday. I could have very easily misread it, though, since the image I saw was rather hard to read, but who knows!
So, uh. If I'm right... happy birthday, River!
Edit: I'm American, but I play in a British (er... okay, Harry Potter) RP where we kinda have to use Britspeak, and I've... kind of gotten used to that. So my brain somehow ignored that there are not 19 months in a year and read 12-19 as being the twelfth... d'oh! I'll make another post on her ACTUAL birthday. XD.
