Heartwarming / Channel Chasers

• Even though they hadn't yet learned Timmy wasn't responsible for trashing the house, the second they found his note declaring he was running away from home, Timmy's parents dropped everything to go look for him, showing that Timmy's parents do care about him.
• As sad as Timmy's last ditch plan was to stop Vicky, it's mildly reassuring that^note at least prior to later developments in the series Timmy would've held on to Cosmo and Wanda until he was 18. The film Timmy was shown at the start concerning godkids outgrowing their fairies had the little girl lose hers at 16. Combined with the hints about his future and its possible that, when he finally does lose them, it's because he's able to move out of his toxic environment and get his life together.
• Timmy's parents come to the conclusion that wherever Timmy is, he's watching television, so they preempt every show on TV to deliver the message that they were wrong and that they love him. As soon as Timmy sees it, he immediately leaves the TV for good. If you look closely, one of the channels they preempt is showing the Dimmies, the Dimmsdale equivalent to the Oscars. Timmy's parents preempt the Oscars to get their son to come back!
• What little we were shown of Timmy's future^note him aging himself with the remote, and the Flash Forward ending shows that, with or without his fairies, Timmy was going to grow up just fine^note he mentions going to the prom at 17, was part of the football team at 18, and eventually got married and had twins, even if he more or less turned out like his dad.
• Timmy twenty years in the future looking back at a picture of his goldfish and smiling.
• Cosmo and Wanda being the Oddparents of Timmy's kids. Specially Wanda's nostalgic comment at the end.
  Wanda: Like father, like son.
  Cosmo: Tell me about it!
• The simple fact that Timmy would rather put up with Vicky for a few more years than lose his fairies, especially since she was the main reason he got his fairies to begin with. Cosmo sums it up beautifully.
  Cosmo: Wow! He loves us more than he hates her! And that's saying something!
• The first thing Doug Dimmadome remembers about Timmy is that Timmy found Doug's missing son Dale. A rather heartwarming callback and humanizing moment for an on-and-off antagonist like Dimmadome showing that he truly felt grateful towards Timmy for that one.
