Serenity knew the villains were done fighting and smiled. 

"i think we've done it!" she cheered and giggled. This was her first win, working with the Titans. The feeling of being a hero was wonderful. Except she knew giving an explanation would be awaiting her back at the tower. She already had a back up plan story in her head. Hopefully they would believe it. Serenity didn't know what she would do if they didn't. She pushed the doubts in her mind away and brought her attention back to the Titans. 

"Great job everyone! Do we just wait for the police now?" She asked curiously. She didn't really know what happened after they defeated the villains. She was almost a little embarrassed.
