* Ben's relationship with his father in the Flash-sideways. While the two grew to despise each other in life (with Ben gassing his dad to death), here, Ben takes on the role of caretaker toward his father, even serving him meals in an adorable manner (and [[CallBack putting air into his dad's respiratory tanks]], [[BlackComedy essentially "gassing" him again]]). Although the elder Linus is feeble from sickness and old age, he still shows that he genuinely cares about his son, asking him about his day and expressing regret that he failed to let Ben reach his full potential.

* Boone telling Jack to let him go and releasing him from his promise to save him, after seeing the toll that trying to keep him alive was having on him.

* Jack and Locke's first meeting in the Flash-Sideways. In stark contrast to their rivalry in life, the two men instantly hit it off, with Jack taking comfort in Locke's words about his father and offering him a free medical consult to fix his spine.

* Ben's relationship with his father in the Flash-Sideways. While the two grew to despise each other in life (with Ben gassing his dad to death), here, Ben takes on the role of caretaker toward his father, even serving him meals in an adorable manner (and [[CallBack putting air into his dad's respiratory tanks]], [[BlackComedy essentially "gassing" him again]]).

* In the Flash-Sideways Ben comes to stop Desmond running over Locke for a second time and says: "I will not let you hurt Mr. Locke again!"

* The revelation that in the Flash-Sideways, Jack's ex-wife and his son David's mother is none other than Dr. Juliet Carlson. Where in their lives both Jack and Juliet suffered from nasty divorces, in the Flash-Sideways they are AmicableExes who both love their son. While Jack and Juliet may not have worked out as a couple in life, there's something heartwarming about them being able to help each other address their issues (their divorces and problems with their ex-spouses, Jack's daddy issues, and Juliet's never being able to be there for her nephew) before moving on into the afterlife.
* In the Flash-Sideways, Hurley tells Sayid that he's a good person, even if he tells himself that he's not. Sayid then proves him right by rushing to help Shannon when he sees her being assaulted, even though he thinks she is a total stranger.

* When Desmond tries to stop Jack from sacrificing himself, Jack tells Desmond that he's done enough, and to go home and be with his wife and son, preserving Desmond and Penny's true HappilyEverAfter.

* All of the Losties in the Flash-Sideways remembering their past lives and being reunited, including:

** Daniel and Charlotte's reunion is rather understated compared to many of these, as they don't remember their past lives, but is all the sweeter for it, as it's clear they'll get the chance to have a life together in the Flash-Sideways that fate robbed from them in their real lives.

** Apart from when he choked on the plane, Charlie didn’t have a single flash throughout the entirety of the Flash-Sideways, but all it took was literally just touching Claire’s hand for him to remember everything instantly. Cue adorkable smile.

* Ben genuinely apologizes for having Walt kidnapped. He also tells him he needs him to help his father, implying that there's still hope that Michael can move on despite his absence from the Flash-Sideways.

* Ben finally completes his HeelFaceTurn after Ilana forgives him for killing Jacob. Even after the Man in Black tells Ben that Ilana won't hesitate to kill him so he shouldn't either, when the moment comes, they both hesitate. Despite the fact that Ben killed the only person Ilana ever thought of as a father, Ilana understands his reasons for doing so after he explains them and gives him the thing he has almost craved the most: a place to belong. It's capped off with Ben quietly returning to the camp and helping Sun out with menial chores.
