when Mac goes to fight Tundra, Heather runs off to some closet to inform Alpha with their implanted chips but she sees two cards she does not know (Puck and Marrina) with golden edges. Thing was to me, there were many other cards on the floor in that panel (supposedly Flashback, Smart Alec, Madison). But from what I counted it was more then the members of Beta and gamma at the time. DId you ever wondered if she would have placed the other cards in the message sender what would have happened.
