Dr. Light listened to the plan, such as it was.  Defiantly not as detailed as one of Luthor's, or even his plans.  With most people that wouldn't be a big deal, but with Batman, the guy who was famous for his strategies and attention to detail, it was a huge deal.  Apparently recent events had taken more out of him than Light had thought.

If this was a a normal meeting, he'd be trying to figure out how to take advantage of this weakness to seize control of the group, but this was far from a normal meeting.  Like it or not, Batman was the best man for the job.  They needed him to plan their attacks if they were to stand a chance.  Sure, he'd like to be in charge, but not if it meant his death or Earth falling to Brainiac.

He drifted over to Batman.  "Don't worry, we'll get you old apprentice back.  Brainiac needs them alive, which means that we can rescue him.  We just need to find him."  After that he flew over to meet the various new women on the team.  Batman had made sure to only put Raven on the team with him, one of the few women he wasn't entirely interested in, likely to keep him focused on the mission.  Nice to know the Bat wasn't so far gone that he'd overlook something so basic.

"Hello." he said to Starfire.  "It's nice to meet someone new, especially someone so beautiful and intriguing.  After this mission is over what do you say to getting something to eat?  I know this great place in Tokyo where you can tell me all about your homeworld."  Not that he was really interested in her homeworld.  Honestly, she was the first Tameranian he had met and was curious how they were different from human woman, in multiple ways.  Besides, he was getting tired of unpowered groupies.  He needed a challenge and these super women might just provide the "conquest" he sought.
