The match at WrestleMania was part of a storyline in which Guerrero turned on Mysterio and beat him up after abandoning him during a match against MNM for the WWE Tag Team Championship. Then after a no disqualification match against Chavo, Eddie came out and slammed Mysterio on the steel steps, displaying Eddie's increasing frustration with being unable to defeat Mysterio. Guerrero and Mysterio continued to feud, with Guerrero threatening to reveal a secret he and Mysterio shared involving Mysterio's real life son Dominik, unless Mysterio deferred to Guerrero's authority. Guerrero later revealed that, in the storyline, he was Dominik's biological father. The storyline went that Guerrero knew Mysterio was having trouble starting his own family, so Guerrero left Dominik as a baby with Mysterio and his wife Angie to raise. In subsequent weeks, Guerrero threatened to take custody of Dominik, drawing up custody papers and having his lawyer present them to Mysterio. At SummerSlam, Mysterio defeated Guerrero in a ladder match for the custody of Dominik. Their feud ended when Guerrero gained a victory over Mysterio in a steel cage match on the September 9 episode of "SmackDown!". On November 13, 2005, Eddie Guerrero was found dead in his hotel room in Minneapolis, Minnesota. That same day at a WWE "Super Show" where "SmackDown!" and "Raw" were both taped, Mysterio gave an emotional speech about Guerrero, and in a show of respect removed his mask (though he put his head down, so no one could see his face). Mysterio went on to defeat Shawn Michaels in an interpromotional match later that night. After the match, Michaels and Mysterio hugged in the ring and Mysterio pointed up to the sky, crying, in memory of Guerrero.
