So, we know that Annabeth's birthday will be revealed in HoH because Rick said so on Twitter. He has also said on Twitter that he doesn't assign characters' birthdays unless there's a reason to within the book, like Percy's and Jason's. My question, then, does anyone have any thoughts on why Annabeth's birthday would be revealed? I came up with three possible scenarios:

1. Her birthday is in July, so it occurs while they are in Tartarus (happy birthday to her--NOT!)

2. Her birthday occurred during the months they were dating, before Percy got taken, so somewhere in August-December, and it gets brought up because there's some memory related to that

OR

3. Her birthday occurred after Percy got kidnapped by Hera and before they got reunited, so January-June, and possibly it gets brought up because she or Percy is reflecting on how he missed her birthday.

These aren't groundbreaking theories or anything like that, but I thought it was something interesting to consider while we wait for character art and the book. Anyone else have thoughts about this??
