As he arrived at this thought, Roland thought that the possibilities were high. Although he did not know their reason for staying all at those C-Grade Cities, right now, Roland was not willing to find out yet.
He thought that his strength might not be enough yet, so he doesn't want to think too much about it, lest it would manifest to him.

At this moment, Roland and Stacey still did not know that the 'hearsay' and guess actually contained the truth.
