Yes, even Atomic Betty has fuzzy feeling scenes that make you go "awwww".
* Just these heartwarming scenes from the Christmas Special:
** Betty realising the man she's run into on the No-L 9 is her long-lost grandfather.
** Beatrixo reuniting with Jimmy after 30 years.
** Mrs. Barrett reuniting with her father.
** Let's not forget the ending song that went along with the special.
** Also, the crowd gathered together with Penelope Lang hugging her father while the No-L 9 light the sky as the planets glow.
* And in the beginning of Season 3, while Noah was stuck in Maximus' lair at the time, he and Minimus were both actually playing together.
