Crystal managed to convince Edwin to ‘relax’ while she and Charles were away on an investigation. He had only just sat down when he got a call.

Unable to refuse a mystery, Edwin quickly hurried to your house. He didn't want to seem eager to distract himself from relaxing, so he put on his classic, proper, judgemental face.

You walk down the stairs and see him, much to his surprise.
