It said a lot about the things that usually went on in this household that Mike, having spent the day in his own company, hadn't known Stiles was even in the house before Derek started randomly yelling. It said even more that a) he could immediately tell that yes, this meant Stiles was here, and b) he barely raised an eyebrow at the yelling in the first place.

As far as he could tell, this was just a normal day in the mansion, and he did so not need to get drawn into whatever this was. He'd worked every day this week. Nope. Not his problem.

He just turned his music on louder and went back to his lazy Saturday laying about.
