Well,
Hui looks like he's having fun--and he's got some excellent texts. Almost too excellent. To my mind, he's conveying the information extemely well.
Not that I necessarily want to make a tough job tougher, but... it might be worth considering for future iterations, if we want to keep upping the difficulty level, so as not to have "set texts," that a Ghost can only use a quote once per game--i.e. no repeating that extremely useful "Innocent" quote from UT.
A suggestion for the future--not now!
