List of 7 iconic Danny Reagan moments from the Blue Bloods franchise
7. Danny's therapy session

Danny Reagan from Blue Bloods went through a therapy session in Season 8’s premiere.
During the therapy session, Danny Reagan reveals his feelings of guilt over Linda's death, who died in a rescue helicopter crash. His voice is heavy, and he talks slowly as he confesses that he was not home enough and it was his fault that he was not there. It is like the shifting of the air when he refers to May 28, the date she passed away.
During the 08:30 timeframe of the episode, the therapy session starts. David Wilson Barnes, who plays the police psychiatrist, Dr. Dawson, asks Danny,
“Why do you really want to hang up your shield?”
Danny replies,
“Why does everybody care whether I put my papers in or not?”
Donnie Wahlberg played this moment with quiet power. He didn't overdo it. His pain feels real, not scripted. You see a man who is strong but broken, trying to hold it together. That kind of honesty makes you feel for Danny and admire Donnie’s skills. He adds subtlety to any given scene, and that is what makes you a fan.
