I meant Nora lol. I swear they mentioned 30 years unless it was that she is from 30 years into the future.
Barry goes missing in 2024. She said she doesnt remember him so lets say she is 2 at that point, he is still missing 25 years later. Assuming she travelled back around the 25th anniversary of his dissaperance that would make her 27.
Yeah Im guessing they did that to show how sheltered she was by Iris growing up and to make her so look so much less experienced and mature than Barry so that he can play the father/mentor role this, maybe they felt it would be weird to make them equals.
