Where the hell did the Gatecrash and Rocket romance came from?

How Did Rocket Not Die is, unfortunately, a question that can only be answered with "Technet magic bull☠☠☠☠." Convenient Technet powers turn out to be the key to the entire heist, and poor Rocket ends up loathed by everybody. Of all the unsatisfying bits in this finale, I'm most irritated by Al Ewing's coy ambiguity regarding Rocket's Halfworld days. Mr. Ewing probably *wants* to retcon the dark twist Abnett and Lanning gave them in Annihilators, but he doesn't have the time to do it properly. Instead we get wishy-washy "who's to say what really happened" waffling. And the fact that all my attention is focused on a Halfworld dream that has *very little* to do with the main heist plot just underlines how underwhelming that plot was.
