Cal smiled and waved when he was aware of people but once he started letting echoes draw him, they pulled his attention.

BD's whistled reply was almost defensive. He was confused, not scared, thank you. Not that much scared him. He had a bad habit of rushing in because something looked interesting without considering whether or not it might also be dangerous.

Cal came back when he could pull himself away from echoes, deciding he had as much real information as he was going to get here. By this point he was visibly drained. "It all seems just. Normal." He raked his fingers through his hair and then knelt down besides BD to give him a pat and allow him to climb back up. "Some stress over those Nightmares seems to be the worst of it."
