What is she even doing in Reverse London anyway?
Bruno Bagnyfe, is some kind of wetworks operator. He brought Marcy to Reverse London and is going to use the havoc wrought by her dragon as a screen to capture Balgo. Then kill him once the reward money is offered.
He didn't give Marcy the dragon though. She found it in Front London. She's just one of those rare, naturally gifted people with a lot of man's: a Watcher.
The girls grab Marcy and Balgo and hightail it out of there.
It doesn't take long before Bruno tracks them down.
