Estela and Dragonetz' Big Damn Kiss. It spontaneously happens when they're practicing a love ballad.
Consumating their new relationship shortly afterward is beautiful. Because of her traumatic first time, Dragonetz is endearingly careful not to hurt her and she has faith that he would never hurt her. The physical stuff is kept to a minmum and their love for each other is paramont.
Al-Hisba's plan to save Dragonetz and especially the letter. He didn't need to set all that up. He could have finished his mission and left the guy out to dry. Instead, he made sure his friend would become survive and become wealthy.
Estela's first original song is inspired by Arnaud's death. She made sure he would live forever in her lyrics as a gallant hero.
