It wasn't often that Mia was in costume at this time of day, but she had some information to collect, and it was far easier to do that in costume. It was on her way back to her place to change that she heard the commotion. She stopped at a good vantage point to assess the situation. When she saw the costume and the question mark her eyes narrowed.
"You have got to be fucking kidding me." She stated under her breath as she pulled out a phone and began recording. She just needed a few seconds to send to Oracle for an ID.
When she saw him show up though, Mia was going to go ahead and head home. There was no way he wouldn't have this under control. That was until she saw the girl giving him the slip.
Mia hopped into action. From her spot she timed it and sent an arrow towards the girl timing it so the small grade explosion would land in front of her.
