[the first note is left unsigned, but the handwriting is undisguised.]
To Kay Faraday (or anyone who knows her):
If you're here, Kay, please respond to this ASAP.
Otherwise, if anyone has seen her here at any time during the past few days, please tell me. I'm highly concerned about her.

[the second note is folded over neatly and simply addressed 'BADD' in giant letters.]
I hope you've calmed down since second shift.
We need to talk. Face to face. And this time, no acting like I'm the grim reaper. I don't need you embarrassing me in front of the whole institute again.
...Seriously, though. You really freaked me out, Badd. Are you okay? Please respond. I have to talk to you.
