Yup. As a kid that stuff didn't even register, but good lord, imagine the shitstorm if Beckett so much as kissed a girl while pretending to be somebody else's SO in Quantum Leap 2016. And you know, rightfully so. In retrospect, through adults eyes, that's pretty creepy. Imagine being the person to go back into their body. They just lost track of days, weeks, even months. While being gone, all this cool shit went down that they weren't a part of. Oh, and the body snatcher responsible banged your SO.
And, IIRCC, there were two versions. One, the displaced person was wholly unaware of what was happening. They basically blacked out and woke back up missing a chunk of their life. Again, with a banged O who is wondering exactly where their SO picked up that trick with the pinky. Pretty scary, right?
But not as scary as version 2. In some parts of the show, wasn't it hinted at, or shown, that the displaced person watched it all go down? So, they were 'a part of it' but not in control? Isn't that the scariest shit ever? You're taken over by a mysterious force and made to do all this shit you have no control over. That's not the stuff of a lighthearted, Jesus-friendly sci fi show. That is some straight humanity horror, right there.
