Did a speed read, but from what I could tell it was the worst issue of the story. Had a couple nice African backgrounds, but Tchalla would have to be of below average intelligence for this flashback to work. Not to mention the terrible placement for a flashback. It could have been put in as the sequel issue to when he got back to Earth. I can't believe an editor signed off on it.
The entire space arc from before he got back is equivalent to then first arc. Completely unnecessary.
