Fans watching Mighty Morphin Power Rangers: Once And Always may have noticed the mention of J.J., Kat Hillard-Oliver's (Catherin Sutherland) son as she's teleported to the Command Center. It's a quick mention, but the last time J.J. was mentioned on air was five years ago during the 25th-anniversary episode "Dimensions in Danger" during the Super Ninja Steel season.

During that scene, it was Tommy Oliver (played by Power Rangers icon, the late Jason David Frank) telling his son to put away his bike. There was a voice off-screen that simply replied "Sorry, Dad." While we don't hear J.J. in Once And Always, Kat mentions that they don't have to tell her son what happened to her and his dad during the recent events to worry him. It's unknown at this point if J.J. knows his parents are Power Rangers, but one can assume it's hard to avoid coming to that conclusion.

The relationship between Kat and Tommy was hinted all the way back in Power Rangers Zeo with the two having to be "married" for a class project. Kat even borrowed a baby named Joey to give the project more realism. At this point, Kim (Original Pink Ranger Amy Jo Johnson) had already sent Tommy the infamous Dear John letter from Florida, where she met someone, ending their on-again-off-again relationship.
