One thing that struck me in a weird way was how Fennec was handled in Book 2. We never see how that wannabe Bounty Hunter gets the Information on Mando, so this could be a bit of a leap for a first time viewer.
Yeah, him gunning her down and getting the info on Mando is not something I would be opposed to being reinserted into Book 2. I went with it because I have seen the original show though, but it could be a bit of a head scratcher for someone who is watching the series for the first time with fresh eyes.
