I grew up watching the Flash (CW) and it was my favorite show, and I've recently started reading comics, and I've gotten to Flash: Rebirth. I have this question (or issue) concerning some logic in the story, and I promise you it's not 'what's Superman's Kryptonite' level of stupid (if it is, please be gentle 😅). It's something that I don't understand or maybe I choose not to, but why are the speedsters' lovers made into their lightning rods to ground them (to make it possible for them to leave the speed force)? Doesn't it sound too ridiculous for a speedster to be unable to leave the speed force because he never fell in love?
