It was a special deal cause they moved to a new night. The second ep was called "Fire in the ice"
When a volunteer fireman is murdered at an ice rink, Booth and Brennan begin the investigation, but Booth must recuse himself due to a conflict of interest. When details come to light, Booth becomes a suspect in the homicide.
A little more the reason Booth was a suspect because the firefighter was on a rival hockey team, and during one game Booth hit him because he took down one of his guys, and broke booths hand. A month later they find the victim, Booth recognizes the necklace he was wearing and excuses himself as he would be considered a suspect. Also professional Hockey player Luc Robitaille had a cameo.
This is all I am going to say, I refuse to give out the killers name, I can't stop anyone from doing it, but for those who didn't know about it, I gave the gist of it, but there was alot more to it.
