Having read Catalyst, I’m pretty sure the Force sensitive character is Lyra Erso in the opening flashback. As far as TPM characters go, I wouldn’t be surprised to see Panaka as a Moff or officer or something.
Joefavs does Catalyst explain where the Erso’s run off in hiding to before Rogue one starts? Does it name the planet they go to?
Because Felicty Jones could not talk about her favorite planet in a recent interview and also in the article from making star wars site. It is called planet X and there is also mention of planet x aliens which the article assumes or explains to be the death troopers.
Not to mention that highly suspicious map we were served from Entertainment Weekly. And also a suspicious name given.
