My dear sister,

Don't panic, I'm still alive. And no, I have not been avoiding you. I have been avoiding the things rampaging through the City with little regard for whose important research they may be interrupting. For fear that you might conduct a manhunt or similar rampage across the ship if I don't contact you, I suppose we should meet somewhere so that you can see for yourself that I am still alive, well, and in no need of nursemaiding.
