Selia Timeline and Summary

Selia invites Princess Ani over for tea with her mom. It turns out the princess isn't so interested in making small talk and would rather be out riding with her dad instead, though. Selia gets annoyed at Ani, but what can she do?
On the road, Selia joins up with her mistress, Ani, and thinks things will be better when they get to Bayern. She even tries on Ani's fancy dresses one day and tells Ani to get lost when she finds out. This is a big no-no and Ani flips when she finds out, mainly because Selia is all cagey about it.
One day, Selia and the guards overtake Ani—Selia is going to claim she's the real princess once they arrive in Bayern.
Selia and her traitor-guards hang out in the palace with the king, and Selia is all dressed up in all of Ani's fancy clothes, pretending to be the princess.
When Ani shows up at the palace claiming to be the real princess, Selia says the exact opposite: Ani's the wannabe.
The king bounces, telling the girls to handle this between the two of them, and once he does, Selia comes clean to Ani and warns her to back off. Good thing the king's secretly listening from the other room, though.
Now that everyone knows Selia is just a poser, she scrams. Good riddance.
