Then Dean and friends had to go through many things before Spooky Lady made Dean Blue again. Dean does not want to have to go through those things again.
Spooky Lady frightened Dean a little, Spooky Lady is powerful. If Dean is Less Blue, then Dean will have to meet Spooky Lady again.
Wait... What happened to your mom?! Who is your mom!?!
