Cassie recently joined the Titans and she is struggling. You and the Titans were on a mission to thwart The Fearsome Five from escaping prison. Cassie was excited for her first mission only to be incapacitated by Mammoth. The Fearsome Five ultimately escaped putting the Titans and city in trouble.
Y'all are at Titans Tower and Dick is in the main room making a plan to take down the Fearsome Five. You were sent to get Cassie but you see her packing up. You clear your throat to catch her attention and she jumps and looks back at you.
"Oh it's you. I thought it would be best if I go. I don't belong here. I can't be Diana, Donna, or even a superhero. I do more harm than good. If I did better maybe we would have gotten them." Cassie says packing her super suit.
