Luke's expression falls a bit, his face not making it entirely known what he's thinking about. Really, he's thinking about the three names. So, Guy's come and gone, basically. The two of Tear thing is... kind of strange to think about. It's already weird having so many of him having gone through this place. And it's strange enough with there being so many green-haired replicas. Adding Tears to that, as well...

He listens to the next part, slowly giving a sideways glance to Asch. Luke watches him, in silence. It's kind of nice to see him returning, even if momentarily, to his old self. It gives Luke a twinge of confidence; and, maybe even a little hope.

"What can I do to help?"

He turns to Asch, his expression completely serious. Luke wants to stop this just as much as the next person. The replica simply needs to be shown where to start.
