I think you should include Dr.Bernard Klein, he's always been usefull both in the 3rd&4th season and fanfic for the science/medicine stuff.
IMHO in your putting Mayson in the good guys list, Scardino should be in the same list. No that I like him ("Please call me Daniel"?!

)but in some way he was Mayson's counterpart/opposite (not sure how to explain it)so he wasn't exactly a bad guy...
