I believe that Wolverine's attraction for Jean Grey resides in his love and friendship of Rose. Wolverine also falls in love with Heather Hudson when she and her husband James take care of him. Gotta love the redheads!
Logan X's forum posts
When reading Wolverine Weapon X, we see that the Professor runs Weapon X. However, there is an unseen person (higher up the food-chain) that comes into contact with the Professor via phone. The Professor is just middle management. My guess was that it could be one of several people: Nick Fury, Professor X, Mr. Sinister, or Aldo Ferro. Now, with current comic books, more so in Wolverine Origins, my best guess is that it has always been Romulus.
