Kratos put the finishing touches on the sector sketch just as Lingormr and Castiel were finishing up. He gave a curt nod to Lingormr as the other man departed before turning back to Castiel.

"I see." He made a note to check the bulletin board before heading back to his room for dinner. Castiel would probably do the same, but it wouldn't do any harm to have two sets of eyes looking for any last notes from Rapunzel. "Do you two need to speak privately first? I can delay my arrival."

This potential third helper was probably the "brother" that Lingormr had mentioned, in which case, there were probably a few things they wanted to discuss that Kratos had no business hearing. He couldn't be totally sure, though, and Castiel didn't seem to want to say anything more.
