Yeah, but you can mix it up and have that come about in another way.
The realisation of the element? Here's how the realisation happens in each:
Dak: His best friend shares a terrible secret with him and asks him not to tell it. This particular secret was that somebuffalo was planning to kill the chief and usurp the rule of the tribe. Dak's friend trusts him very much, and Dak doesn't want to break that trust, but he ends up having to tell the truth.
Sera: Sera hates gryphons, for something that multiple of them did to her family a long time ago. However, she gives Gilda a chance, and ends up liking her... Until Gilda and Dak decide that the only possible way they can get Sera to overcome cruelty is by getting Sera to hate Gilda and subsequently putting Gilda in a life-or-death situation where only Sera can save her.
Kang: Kang doesn't believe that these "elements of harmony" mean anything, but he accepts the pendant anyway, not wearing it. Gilda, Dak, and Sera facilitate a plan that causes nearly all of the town to fall into poverty. The only financially untouched cranes are Kang and a few others, who won't let go of their money. Gilda and friends have to find the pendant, not get seen, and nudge Kang in the right direction, before getting the pendant on Kang just as he gives everything up. Also, somewhat irrelevant, but Kang still doesn't believe the elements actually mean anything at this point.
Smee: Since Smee won't accept the element at all, they have to persuade him to do so. However, they can't think of anything that would cause Smee to have to face his anti-element. Eventually, Dak realises that if they hadn't tried to force the realisation, it would have been a lot quicker and would have much less loss, so they take their hooves completely out of it. And of course, the day after, the most depressed member of the waddle decides to commit suicide. Smee at this point is in despair and is finding it so hard to laugh, but he realises that he must break out of it and keep his friend from suicide with laughter.
Veninde: This one isn't fully thought out yet, but it has the basic gist of Veninde continually trying to make friends with the most unfriendly member of her herd. Eventually, the member is so angry at Veninde's efforts that he rallies the rest of the herd to force Veninde out. However, she figures out how to strike his heart and she makes friends with him.
Each time the process is different. With Dak, one's life isn't directly at stake. With Sera,
Gilda's life is at stake, and Sera has to overcome hate. Kang comes with the added struggle of getting the pendant onto him, and no bird's life is at stake. Smee's anti-element adversary is inside himself and with another penguin. Veninde's adversary turns out to be the
entire tribe.
