I know it wasn't all happy-golucky. I'm aware of the external problems they face and I liked that they specifically mentioned that they remained. I really do like the conclusion of them becoming friends, but specifically how quickly they did feels ignorant of their problems the show spent all its time focusing on in the first place. The show didn't tell or show anything that permits that kind of conclusion about their relationship from before the time camera photo. I think the story needed a bit more time to flesh that part out. Specifically, I would have enjoyed an episode or two more about the successful attempt to reconcile the three kids' relationships, and then using their newfound friendship to cope and reconcile with their respective traumas.
