Last night was the season four premiere of The Venture Bros, and already the season four spoilers are beginning.  Illustrator Rick Lacy recently revealed on his blog some concept art for a new female lead on Venture Brothers.

According to the cryptic file names he used, the character's name will be Nikki Nightgown and she'll be in her thirties and apparently taller than Dean.  I know, we're master detectives on the case for you.

Just click to enlarge any of the following concept art and then sound off in the comments for your ideas of who Nikki will be.  Good guy?  Bad guy?
