Matt wasn't in much of a preachy mood, so he wasn't going to be subjecting anyone to any spiels in a situation where angels feared to tread. Matt wasn't in much of any sort of mood. He just sort of wanted to keep on going until he couldn't anymore or someone stopped him. If he could be kind along the way even in the face of guaranteed suffering and insurmountable odds, at least he'd die happy.
"Not hungry. Just going to- keep going. Unless we're at a dead end? I kind of assumed this- right wall just keeps going." It's not like he could feel any sort of breeze coming from the sewer. Matt had been counting his steps. He'd at least double back quicker than how much time he's spent moving forward.
