Em: Love hurts. Get used to it.
- The Mysticons' friendship in general. They all come from different backgrounds, and even though it takes a while, they form a close bond.
- If you watch later episodes, it's difficult to see who was friends with who at the start of the series. This is in contrast to the first episode, where they were still in their little groups at the end.
- Choko becoming the Team Pet not just for Zarya and Piper, but for Arkayna, Emerald, Doug, and Malvaron as well. While Choko still goes with Zarya most times, they all treat Choko as their pet, praising him when he does something good and hanging out with him.

Episode 2: How to Train a Mysticon
- In Episode 2, knowing what Arkayna is going through, everyone, even Zarya, agrees to back her up, and considering every other episode that follows, they make sure to keep to their word, never abandoning her once.

- Also, the Mysticons just hanging around. It's a small one but considering the fact that they started out as enemies (due to Zarya and Piper having to steal the dragon disk from the palace), it's nice to have them spending time together.
- Also, part of Zarya's list is "people who pick on others". This shows that even though she acts tough, she still cares about those around her.

Episode 8: Lost and Found
- If the first part of Piper's nightmare is based on her memories, which is assumed to be true, then that means that Zarya (who was on the streets herself), was willing to take care of a girl she just met.
- Despite Zarya getting kicked off the team in the Cliffhanger Downer Ending of the previous episode, when the Mysticons learn that she's missing, they're all willing to help find her.
- Emerald tells Piper that her and Arkayna were there for Piper too.
- What makes it better is that both Arkayna and Emerald were willing to find Zarya, and only abandoned it to get the codex piece back. It makes it clear that they don't want to replace Zarya, but want Piper to be alright.

From the Chapter books
- In "The Secret of the Fifth Mysticon", Em was confident that Doug would be the Fifth Mysticon, and even suggested that Doug go with them on the mission.
- When Arkayna was hesitant to go to the Chillwaste, as they didn't have a lot of information, Zarya said they should, as a Mysticon needed their help.
- Also, the Mysticons were willing to go with Em to save the Fifth Mysticon without talking to her themselves, trusting Em. When Adakite turns out to be using them to escape her prison, and was never the fifth Mysticon, no one holds it against Em.
- When the Mysticons and Doug see statues of the old Mysticons, there are a couple heartwarming moments. Piper mentions the Mysticons Ranger and Striker being "buds forever", and Em reassures Arkayna that she looks as commanding as Irmani Firewing did.
- Em and Piper singing to cheer up Doug.
- Arkayna cheering Em up after they realized that Adakite Flowstone wasn't a Mysticon.
- Arkayna and Zarya's talk at the end of The Stolen Magic when they finish talking about the events.
- The end of the novel counts, as Zarya is thinking about how anything that looks like it could split her and Arkayna apart is "just smoke and mirrors".
- Also, when Zarya goes on the mission to defeat Dreadbane, Arkayna wants to tell Zarya to be careful, but holds back, knowing that Zarya felt that Arkayna thought she can't take care of herself without magic, and telling Zarya to be careful would make it worse.
- In "The Diamond Curse", Arkayna refuses to apologize and be ashamed of her friends, despite them not fitting in with the other wealthy passengers on the train.
- Also, after defeating the hexbeasts, Arkayna asks if they need to talk about any of it, and expresses concern that people believe Arkayna really thinks what the hexbeasts said, such as her seeing the other Mysticons as staff. The others quickly say that they're fine, and that the voices don't bother them, eventually leading to a group hug.
