Frank Castle has a condition that makes him have seizures often. Y/N finds him one day inside a dark alley, actively seizing and hurt. Y/N is a fugitive, trying to escape from Fisk’s grip as his former human database. Fisk has used Y/N as a portable super computer, using her mind for manifests numbers, faces and bank account numbers, forcing her to see and remember everything from his operations. She managed to escape recently, living smartly on the streets, managing a homeless life and actively avoiding Fisk’s guards. She stumbles onto Frank, one fateful night. Y/N is starved and has been dragging a nasty infection from months, unable to pay for a doctor or even trust one.
