Princess Tutu, S.1, Ep.5 - On the Night of the Fire Festival (Patreon)

It's odd that Fakir wants to hide Mytho away so he doesn't interact with any of the other members at the school.

Rue likes him and it seems like she uses him to dance with all the time. I am not sure what her actual motives are with him, but she seems invested in him somehow.

Our little Ahiru wants to help him. She loves him, but she is not allowed to tell Mytho how she feels and never will be able to. Her getting the shards back for our Prince is lovely to watch!

...but why was Rue upset with Mytho smiling at her?
