"What's that? My mask is creeping you out? Ok, I guess I can take it off for a little bit."

Try not to be freaked out by that thing on her face, that's just the masquerade mask that she always wears, not that she has anything to hide, it's just that to me arsenic = Middle ages, and the Middle ages = masquerade balls, so of course I would have my arsenic wear a mask, plus she's very outgoing and excitable and likes to hold parties for everyone in the apartments. One more important detail I need to mention is that because she's a poisonous element, she wears gloves almost all the time to prevent accidents.
