1) You've revelealed previously that Lietutenant Marvel and Sergeant Marvel both left the Team in the same calendar year. Did they both leave at the same time?
2) You've said that if Mary had been able to appear in Satisfaction, she would have appeared as both Mary and Sergeant Marvel. Does this mean she left the Team for reasons other than having to give up her powers, or was that something new developed in the years after season two?
3) When did Mary stop using her powers (prior to starting again in Kaerb Ym Traeh!)?
