It has been three months since her parents last answered her calls, and Erin is officially worried at this point. They might be disappointed in her life choices but that hasn't caused them to completely cut her off yet, in fact she'd expect an actual intervention before being cut off completely if they ever decided they couldn't conscience it anymore. Even if she does such things as working at free clinics and donating to charity for more than tax reasons, the horror, she's still their genius daughter and heir.
So, this is very weird.
Luckily, she does have a contact in the little nowhere town where they were working. Given the hints of Top Secret Projects and the mysterious disappearance and the lack of information coming out of the town, she'd ended up coming to the conclusion that the only way to get to the bottom of all of this would be to move to Strangerville herself.
She heads to the hospital first thing when she arrives into town, intending to check in to make sure all the paperwork had gone through on this end. The receptionist directs her to the office she's looking for without hassle, so she takes the stairs up to the second floor and knocks on the door.
