Luke actually gets it, loud and clear. He nods, before noticing the ghost of a smile, which... is kind of weird to see. So he'll pretend he didn't, to save Asch from possible embarrassment at being seen and himself from getting glared at.

Speaking of weird things, Asch had somehow managed to... cheer him up. He smiles, looking to the side.

"You're right... I will," he lets out a soft 'heh', "Thanks, Asch."
