OK, I've decided to do what I did with "Batman Eternal" and "Earth 2: World's End" and just read everything at once so that I can be done with it. Here we go.
I honestly have no idea how we get to where we are at the end of this issue. At the end of last issue, it appeared that Deimos was planning on freeing Brainiac to get power as a reward. It wasn't clear why he wanted that power and what he was going to do with it, but it seemed to be the deal.
However, in this issue, it's totally unclear why he summoned Brainiac. He clearly swiped enough power from the Time Masters to hold off the Wonders and Warlord, so it seems unlikely that it was just for power. His only interaction with Brainiac is to taunt him by revealing Telos' origin: he was originally a man who agreed to serve Brainiac if he spared his family and people, not a planet made sentient (as he believed himself to be). But, King doesn't explain why (other than taunting Brainiac) Deimos decided to return Telos' memories to him or why he summoned Brainiac in the first place. In fact, both actions seem to undermine Deimos' position. The Wonders now consider both Brainiac and Telos as viable (if troubling) options to defeat Deimos, whereas they were previously on their own. Given that Deimos is now trying to unite the cities under his leadership, it seems beyond foolish to throw a bone (or two) to the rebels. (Also, I should mention that we never learn why Brainiac is imprisoned in the first place.)
I could continue, but let's stop there. Only three more issues...
