Zero no Tsukaima: Princesses no Rondo - The Eastern Pursuit!

Colbert is alive. He was saved by Tabitha before death. Using knowledge from the dragons plumage he constructed an air ship with an advanced engine. Louise is still suspicious about what she witnessed between Henrietta and Saito and enlists the help of Siesta and Tiffania to capture Saito and force him (by using magic) to reveal what happened the previous night. Pursed across the ship (under the mistaken impression the magic will remove his clothes) by the increasingly desperate trio he is finally cornered and it is revealed to all about Tabitha’s involvement in the previous nights escapade. Saito and Henrietta have difficulty meeting each others eyes throughout the episode but the episode concludes with Louise’s resolution to trust Saito while Siesta is still concerned.
