Someone called me a comics professional today. I’LL SHOW THEM.
honestly my headcanon for lexa being in the city of light is like, I have no idea why she was there either, but maybe like she and all of the past commanders just live in like this really swanky penthouse apartment together, like ALL of them. and they all kind of got the bat signal that clarke was there at once and all of the big hulking past commanders turned to lexa and were like "GO GET YOUR GIRL!" and lexa ran into her room and grabbed her gear and warpaint, and went off after clarke.
