Why

Houston had no idea why he was suddenly having to shift jobs or go someplace that was three hours away from where he had been assigned. 

He had tried to ask Ian what was going on but the other didn't say anything. He just handed him the papers that held on the information that he would need and told him he better leave quickly if he wanted to make it on it. 

His boss didn't even try to look at him as he spoke. He just kept his gaze fixed on his computer the whole time. Too focused on whatever he was doing to say anything to the other. 

Chester didn't even understand what was going on when he explained the situation to his friend. It didn't sound like it was part of normal protocol for this type of thing to happen. 

The detective couldn't do anything though except go to where he had been assigned and ask what was going on and why they specially requested him when he had something more important that he needed to finish dealing with.
