#this means that she would have turned 14 during four-month Nublar timeskip

Okay, back to age speculation and lore:

I assume Brooklynn would be twenty if she had survived?

Because she helped Yaz in Texas, iirc, and that was fourteen months before the show. She might have traveled with one of her dads, but she seems more independent, and I think you need to be eighteen to drive yourself out of state.

Though I don't know if Texas and California have different laws, OR if she is actually from England, and if that is different.

Or maybe she just has a fake driver's license and is a Rebel like that.

I presume she was nineteen when she was attacked (MURDERED), because the casting call was for a nineteen-year-old.

Given the span of text messages (5/3/2022 - 9/30/2022), we can pin her birthday at some time between May and August.

UNLESS MY EVIDENCE IS FLAWED.
