the main character is revealed to have been using a specific drug to build a tolerance incase she’s attacked again. when this is revealed, the doctor asks to lift her sleeve to reveal where she’s been injecting, and you see some marks around the crease of her arm, which could be seen as self harm or just a triggering scene for someone who deals with that. it only lasts a moment so you could just look away, but it’s up to you.
