If J'onn has touched her, Laurel is from the original Earth-2. In the new multiverse, Laurel probably belongs to the New Earth-2 but ended up in Earth-Prime because she was on Earth-1-- hey wait, didn't everyone who escaped their Earths' destruction retreat to Earth-1? And Earth-2 was the first destroyed so she escaped with the Earth-1 Oliver and Diggle? I guess she'd only be an Earth-2 person on Earth-Prime for plot convenience or something. Unless Damien Darhk never killed her in the Earth-Prime timeline. Or, since we haven't seen her in Crisis Part 5, maybe she's on Earth-2 and someone brings her to Earth-Prime? I have no clue.
