The death of Aaron Hotchner's (Thomas Gibson) ex-wife Haley (Meredith Monroe) in Season 5 is one of the most heartbreaking moments of "Criminal Minds." That tragic storyline is revisited in Season 9, Episode 5, titled "Route 66." Hotchner, who is recovering after surgery, dreams about Haley and George Foyet (C Thomas Howell), the serial killer who murdered her. His moments with Haley, while scattered in bits throughout the episode, make for the most tear-jerking scenes, with a conversation the two have about their son being especially moving. Eventually, when Hotchner replays her murder, the hurtful memories are relived all over again.
Redditor u/definitely-not agreed. In a thread dedicated to the series' saddest episodes, they wrote, "one of the saddest episodes IMO is season nine episode five, route 66. the way he was trying to help her and though the wound wasn't real, he still tried. it breaks my heart. and at the end when he's like i don't want to leave you."
Moreover, the case at the heart of the episode, which involves a father abducting his own teen daughter to take her to a better life, is also brimming with sadness. The emotional conversation between the father and the daughter at the end makes the episode a particularly painful one for many. On another thread, u/caitlynat specifically cited this heartwrenching moment, writing, "... when the daughter went back in to talk her dad out of what his father did was so sad."
This double whammy delivered a strong punch of emotions to the fans, making it the most heartbreaking watch of Season 9.
