Costigan cared more about his word to make the effort than actually offending Bakura with the wrong name usage, which was why the slight tilt of the head in unnecessary forgiveness irked him just a hint. He was glad when the subject returned to more practical matters and gave a shrug at the thought.

"I know a couple people with better connections. Kyle and Dick, for example." Normally he wouldn't give names, but Bakura was the nosy sort and Costigan would rather give him a couple good people to follow than have the guy digging for his own secrets. "Dick's the head of Wayne's company now. They should have some labs or somethin' that can look into it."

Realistically, it was a possible route, but Costigan was much more likely to ask Evandau and leave it at that. Maybe Kyle, if it wouldn't distract him from his own information search.
