we're the troubled kids (arrow/flashxreader)

(yn) lives in central city, in a school for troubled kids.
but before that, she was part of an experiment.
an illegal experiment, for 15 years.
she escaped but for how long.
for how long will she be able to stay hidden.
and how long will it take for a few certain superheroes to get a bit suspicious.
