Question: Which former partner was older when their feud began in 2009? Passage:At Final Battle 2009, on December 19, Kevin Steen betrayed and began a feud with his former tag team partner El Generico, turning into a villain in the process. In 2010, Steve Corino joined Steen against Generico and Colt Cabana. At Final Battle 2010, on December 18, Steen lost a match against Generico that resulted in his departure from ROH. Prior to the outcome, on November 4, 2010 at an ROH taping, Kevin Steen's contract agreement with Ring of Honor ended due to financial budget concerns, which ultimately played a role within the stipulation of the match. Corino soon turned face and introduced his ally Jimmy Jacobs, both claiming that they were good people that could reach out to Steen, and asked ROH for a second chance for Steen. However, Steen, who wanted to redeem himself but was opposed by ROH and its security that came to evict him from the building, ended up turning on Corino upon his return at Best in the World 2011 on June 26, sparking a revolt against ROH which fell into conflict with Executive Producer Jim Cornette, who vowed to rid the company of Steen. Furthermore, Steen threatened legal action if he was not reinstated, leading to Steen ultimately defeating Corino on December 21 at Final Battle 2011 to win a contract from ROH. At Showdown in the Sun weekend, on March 30, 2012, Steen defeated El Generico, with help from Jimmy Jacobs in a Last Man Standing match. On May 12 at Border Wars, Steen defeated Davey Richards to win the ROH World Championship for the first time. Following the match, Corino entered the ring and hugged Steen and Jacobs, as the three men went on to form a stable later named S.C.U.M. (Suffering, Chaos, Ugliness, and Mayhem).
