Wait for Erica to get back

You start to think of some of your friends before realizing that you have no way of getting to them without streaking across campus. Not only that, but they all have exams as far as you could remember. "Erica!" you realize out loud. She didn't have any exams today and what's more, she was actually meant to be back at the dorm any minute now.

The thought of telling Erica about the implant isn't something you're excited about. She would definitely tease you about it, and if she was given owner access, who knows what she might get up to. However, you don't have any other options right now, and you need to make sure you're able to get to your exam in time...
