...I find those are the grumpiest types. Hence 
why Aya is always so grumpy...but Keith here 
takes an extra step, because not only is he 
grappling with who he is as a human, but he's 
debating whether he -IS- human at all. Fun fun. 
Consequently, he's always in sort of a snappy 
mood...here he is yelling at people because 
they're folding to Mu mindtricks (think Jedi 
mindtricks ^^;;), and it's causing his ship to 
malfunction...
