For Good/Heartwarming

Breakaway

 * Buzz just takes to being Erin's Big Brother, and it's so awfully cute.
 * The Convenient Slow Dance, Buzz's singing, and Warp's and Erin's reactions to the whole thing.
 * "Jim" and "Mr. Spock". Erin and Ricki are pretty cute.
 * Erin and Mira talking about their mixed-up love lives. Awww.

The One-shots

 * "He never thought of her as young."
 * The "fairytale" told by Liberty in no. 4 of the Ships 50, and the ending of the fic itself.
 * Warp's return in "33. Too Much".

The Roleplay Arc

 * Buzz's Big Brother Instinct goes into overdrive and becomes his Berserk Button - but you can really see how having Erin around has opened his heart up.
 * He also makes an Adorkable dad.
 * Cora Lightyear calling her daddy "Papa". Awww!
 * Warp and Erin get some pretty cute moments together.
 * The Darkmatters. Can't you just see hearts around the name?
