Zach who saw that also asked, "Who is he, Wilson?" He asked Wilson, ignoring Vernon and Nick who walked into the apartment to check and look for Aidan's whereabouts and handed the body over to Wilson.
"I think he's the professor that Lucas and Aidan are looking for!" Wilson explained to Zach as he stood back up when he learned of the long-standing death of the professor, while Zach just nodded his head at Wilson's explanation.
Meanwhile, Vernon and Nick who walked through the apartment to look for Aidan did not find anyone in the apartment. Vernon looked at a window that had broken glass and blood splattered around it. Vernon immediately checked because he was afraid that Aidan would be dropped from the window. But once again, he didn't get anything when he looked down there, so he felt grateful and sure that Aidan was still alive today.
