 MISC: When Diabolico saves Ryan from the car accident, he tells  Mitchell that he will not see his son until Ryans 20th birthday. In  the following scene, Mitchell bemoans the fact that "for 20 years"  he has dreamed of seeing his son again. The math does not add up,  seeing as that day is Ryans 20th birthday, and the flashback scene  shows a child of at least four.
