Missing Numbers | Robin Buckley x Female OC

Set in season three kind of with the timeline, kind of not. She'd always been there. She just made sure she wasn't seen, wasn't heard. Just like she'd been taught. After being able to tear herself away from the clutches of Dr.Brenner and Hawkins lab, she made a name for herself. After being treated like an object and a possession of sorts for years by Brenner and his team, she'd hated being reduced to a number, she'd known she was so much more. Changing her name, Em Mills, after nearly a month of hiding, decides the people of Hawkins are in need of her aid. But did she really go unnoticed all those years? And what happens when she develops strange but strong feelings towards one of her new friends?
