At "Hell Freezes Over" in 2006, BJ Whitmer attacked Christopher Daniels because he walked out of ROH and The Prophecy in 2004. The two fought at the "Fourth Anniversary Show", but their match was ended after wrestlers from Combat Zone Wrestling took over the ring. Whitmer went on to become a member of "Team ROH" along with Samoa Joe, Adam Pearce and Ace Steel and helped fight off the CZW invasion. At "The 100th", Daniels made ROH history as, for the first time ever, he respectfully shook Claudio Castagnoli's hand after their match, adhering to the "Code of Honor" (Castagnoli then betrayed ROH later that night and joined his best friend Chris Hero with CZW). Later in the year, Daniels became a two-time ROH Tag Team Champion, as he and Matt Sydal defeated The Kings of Wrestling (Hero and Castagnoli).
