A Robbery at the Dance - S1.E20

The King holds a banquet to celebrate the arrival of Lady Dalma at the Palace. Naturally, Dogtanian, Juliet and the Three Muskehounds are invited.

During the party, Athos is inseparable from Lady Dalma, so besotted is he with her. She asks him to accompany her to the bedrooms, as her shoes are hurting her and she wants to change them. Enchanted, Athos accompanies her and stands guard outside her door while she changes.
