(Just to clarify, the story will take place during Season 1)
M'Gann M'orzz (AKA Miss Martian) was training in The Cave with Artemis, Zatanna and Black Canary. Canary had been training them extra hard recently with the increase in super villain activity recently.
Artemis took a kick to the face from Canary and threw her bow to the ground and stormed off. The other three gave chase. M'Gann was the first to catch up to her
"What's wrong Artemis?"
"Canary has been working us to death recently and I'm tired of it. I don't have magic powers or Martian super strength. I'm tired and I'm done working for the day."
Black Canary was about to respond when a commercial came on the TV advertising a new salon in Happy Harbor. They were offering 50% off spa treatments during their grand opening. Dinah decided rather than continuing to train the girls, she would treat
them to a day of pampering.
"OK girls, lets take the day off. I'm going to take you to that new salon for a nice spa day."
With that being said, the girls all changed into their civilian clothes and left for the grand opening of the Happy Harbor branch of the New U Salon
