The theme of the show is heartwarming in itself: You Are Not Alone, because humankind is all connected to each other, and we can do little things, even accidents, that help another person no matter the distances.
Counts as a Crowning Moment of Awesome too: Grace standing up to her friend Sauda's abusive boyfriend in "Safety in Numbers," and when he won't back down, she is joined by the rest of the women in her village.
In "Entanglement," Norah proving herself to her father. So much so that he has warmed up to the idea of her studying abroad in America instead of a prospective bride for a wealthy family's son.
The "Find Celeste" story from "Noosphere Rising". Natalie, a video blogger recently dumped by a jerk boyfriend, helps organize a huge internet movement, to reunite two people named Paulo, and Celeste. In the end Celeste doesn't show...but a cadre of others do, coming from across the globe, to show their support for Natalie.
What makes it even more heartwarming is that Paulo did show, but not for Celeste. He traveled all the way to New York to see Natalie instead, and they go out on a date.Cue the tears.
Veronique being reunited with her parents and the twin sister she never knew existed through Martin's actions in "Zone of Exclusion."
Jake holding hands with Martin at the end of "Gyre."
Also during the first part of Gyre, Martin shows up at Arnie's pawn shop. It's heartwarming to know that Martin kept his promise to be Arnie's friend.
And from that same episode, the scene where the guy on the beach sees the woman from the tsunami and returns her husband's sword to her. It's the scene between the son and the father afterwards that makes the screen all blurry.
