Back at WrestleMania 35, Rey Mysterio was easily defeated by Samoa Joe in their United States Championship match because it was reported that The Master of the 619 was injured and could only perform a short bout.
Reports later suggested that WWE were going to add Mysterio’s son Dominick to the storyline at WrestleMania, but because the match was a short one, Mysterio’s son wasn’t able to feature.
Over the past few weeks, Dominick has been seen alongside his father both backstage on Raw and then last week he celebrated his father’s non-title victory over Samoa Joe with him on the ramp, despite the fact that Mysterio was very close to the ropes with the pin.
This week on Raw, it was made clear that Joe will defend his United States Championship against Mysterio at Money in the Bank since the former World Champion now holds a victory over Joe even though it was in a non-title match.
Dominick has obviously become a main player in this storyline after reports suggested that the youngster had signed an official WWE contract, which meant that he was now able to become part of the storylines on WWE TV in a much more physical way.
Mysterio has definitely enjoyed having his son by his side over the past few weeks, as Dominick has enjoyed his longest stint in front of WWE cameras since the summer of 2005 when he was embroiled in a feud between Eddie Guerrero and his father over his true paternity.
Samoa Joe sent a message to Rey Mysterio ahead of their Money in the Bank bout through his son Dominick when he was able to find the star backstage, which makes it highly likely that Dominick could be the one to help his father become United States Champion next Sunday night.
