The timeline concerning Sean Reagan makes no sense. He went from being a college student with no outward interest in being a cop to suddenly being a cop! He was more of a writer/artist on Blue Bloods which I thought was pretty cool. Apparently he gave that all up, left NYC (as well as his tight-knit family), lost weight and attended the 29-week program at the Boston Police Academy. What I truly don't understand is how Donnie Wahlberg could have read the script and think the BB faithful would not have all of these questions. Additionally, we have already seen Ernie Hudson and Gloria Reuben (both fine actors) in different roles on BB. Why the recasting? Do the writers think we're stupid? Anyway, I find myself falling asleep watching. What was CBS thinking?
