The fact he says Spider-Man at the end...You may think its just Deadpool being crazy but its actually quite smart because 1) if Deadpool was fucking with the timeline, the legend of the "Spider-Man" would be more likely as a mythological story that you would expect to see, 2) assuming people found out about it, it would be a good cover for Deadpool to say it was Spider-Man doing the hijinks with time, and 3) Considering Deadpool's a Mercenary, he wouldn't want his cover blown and Spider-Man is a hero of the people, so inspiring hope with Spiderman is more like him than it would be for Deadpool.
