It looks like the person sneaking around yesterday was Five. She was either a) sneaking around trying to find something and didn't like what she saw, b) sneaking around trying to find Zared (found him!) or c) sneaking around and is just an emotional wreck for no reason. Which is highly possible.
Again with the 'I don't know what possessed me to draw these things!' Seriously. I don't know.
EDITED to show outlined version .-.
...I dunno what's going on with cPanel for M-C.com...
