Ridley also questions the timeline for Jyn to be her mom. "I also don’t know if that would work out time wise” — so let's work it out. Rogue One is set before A New Hope, aka Episode IV, the first movie released in 1977 that introduced the world to Star Wars. It's also after the events of Episode III, aka Revenge of the Sith (the final movie in the trilogy released in the 2000s).
There are about 30 years between Episode VI and Episode VII, which is plenty of time for a character in Jyn's age range to have a child. It could make Jyn a really old mom, but it was noted that Rogue One takes place closer to New Hope at 2015's D23 (which makes sense, since Luke is involved in the stealing of the Death Star plans). Therefore, I think we can assume that Jyn is probably around the same age as Luke. And if she is the same age as Luke, she's the same age as Leia, who also had a child that is Rey's age: Kylo Ren.
Sorry Daisy Ridley, YA BURNT!
