Much to Ty Lee's delight, she's found that some of the ways into the air vents are much bigger than the one in
Azula's room. Now she can keep her boobies!
So if you hear something scuttling through the airvents? It's probably something other than Ty Lee. You won't hear her. Count on it.
Right now, she's in 202, flipping through a fashion magazine. She can't read the text, but look at that! Pretty clothes!
. . . and some really awful ones too. Ick.
