Not you again!
So after the torture that was karaoke and then later having to deal with the...Pippi girl, well...Thomas needed to get out of the city for a short bit. And the arms dealing he'd been working on shutting down in Gotham had a trail that led back to Hub City. After the fiasco last time he'd tried to shut down the arms trade in Gotham (and had a buffoon crash it then think he was helping well...) he needed a big win here. That last encounter had ruined his plans and he'd needed to start from scratch.
