Wolverine is the impromtu addition to thr X-Men that nobody expected. When Xavier arrives at the school with this "new addition to the team" without anyone's knowledge, especially Cyclops' it starts to break trust between the two. Wolverine is not as anyone would expect. When he arrives he's surprisingly laid back, calculated and efficient in battle. Although he's not a great team player, which tests Cyclops' leadership skills to the fullest.
