Yup, both are just as real - something some people couldn’t get their heads around back in S2 either. Quantum duplicates means what once was one gets split into two identical originals - not one original being cloned into a second. Thats’s why Lost Light 2 Rewind was just as original as Lost Light 1 Rewind: apart from the 2-5 years history that doesn’t add up with Lost Light 1 Chromedome’s, he’s had (and had been) the guy’s exact same history hundreds of years prior. Swerve got hit with the metabomb somewhere during the run of this book, that’s why he sometimes acts aware of being inside a comic book (and why he sometimes does the synopsis). You’re right in that Megatron *could* have given away his Star even if he was imprisoned and hooked up to a machine. But Roberts already vaguely confirmed that execution wad the outcome (besides, even without hope of seeing release, would Megatron want to give away his -harmless- Star - the thing that reminds him of the good times, and possibly the only good thing he has left?) Your other 50% jumped into a new universe looking for more adventures?
