Maybe it's Arwen!

"I better talk to Agent #b#p1103003##k of #m101000000# about a new assignment."

"#p1103003# told me she suspects that #b#p1032100##k might be controlled by the Puppeteer, and asked me to give Arwen #b#t4032142##k, which can be purchased at #b#m101010103##k. Her theory was that if Arwen is controlled, then she would dread it; if Arwen is free, then she'd be ecstatic over it... \n\n#i4032142# #t4032142# #b#c4032143# / 1#k"

"Arwen thanked me for giving her #t4032142#, for she was very thirsty at the time and proceeded to finish it in one giant gulp."
