So, an issue of MTMTE that doesn't require discussing Rewind and Chromedome.

Some fairly big things happen this issue, and yet it feels strangely light in the plot department. I think it's because we're still only inching forward in the "what happened to Ultra Magnus" storyline, because otherwise, a good many things happen. There are half a dozen character storylines going at any one time, with all of them competing for limited page space, which probably also helps explain why it feels like things are going at a crawl. At least everything is interesting.
So the lost moon is found, and I doubt that portal leading to it just happened to pop up for no reason at all. Something's behind it, I'd hazard a guess, probably whatever took Ultra Magnus. The billions of sparks all over the surface is an idea that Roberts deserves credit for due to the scale and spectacle of it. And it makes sense. How in the world does a race do anything but kill itself off if thousands are dying in a war and only a few at a time are being brought to life via the Creation Matrix, or whatever. Not that that applies to IDW continuity, which has been largely silent up until now on how Transformers come into the world. In any case, it's a fascinating idea, though it's also very disturbing how just about all the Autobots present seem to have very little respect for the life all around them. They immediately start wondering how the situation could be used to their advantage. They really are a bunch of irreverant jerks, aren't they?
I am also glad to see the Legislators return from issue #2, since we'll finally (presumably) be able to learn what they are and why they're after Skids. And now the other bots on the ship as well. And it's good to see Fortress Maximus out of his cell and part of the crew again.
