This is what we have. The Avengers shows up on the planet to talk to Sun God and the crew. During the time they are talking it skips to this scene...

Banner telling us about the injection and what it does. Then it skips back to the fight. Lol...why did the writer do this? Why did he even include that piece of information in a comic where the universe is about to be destroyed. Why have Banner talk about a serum that he is about to take and explaining what it does and then skip right back to the Avengers and the JLA lol? That scene didn't have ANYTHING to do with the circumstances at hand. Unless he wanted to advise us of a something that was going on during that fight. Why did he showcase Hulk eyes going green. That's not something new to us. THINK!!!
