Drakin has finished his changes (which much thanks to  Shottsy85 ).
With the virus now fully having effected his system, his mind has changed slightly. Until it has run it's course, his new pony self is far more magically inclined and somewhat childish. That's not to say he acts like a kid, but his energy is up as is his desire to play over getting any real work done.
Another symptom of the virus is the loss of any and all swear words temporarily from his vocabulary, making him unable to cuss anyone out. Of course that's assuming he would ever be mad enough to try in the first place.
