Midnighter's high school nickname is Murder Machine.
Oh, okay, forget Martian Manhunter! I guess it is between Tanner and Midnighter!
The Shadow Cabinet Guy disappears (off to his island, he says) to leave Stormwatch to deal with the matters at hand. Tanner heads off to find Apollo and Midnighter while an emergency alarm goes off on board the ship. Something is approaching them inside hyperspace.
Big deal! Everyone in the DC Universe has the power to finish other character's sentences!
Before the fight can play out to the end, the Projectionist wanders into the room. Harry grabs her and enters the airlock, launching himself and the Projectionist into Hyperspace where they disappear in a twinkling gold glow. Unless that was Apollo doing something to them. But it probably wasn't.
On board Stormwatch Headquarters, a recorded message from Harry plays. He has set the Alien Horn thing seen in Superman #1 on a timer. When it reaches zero, the Horn blows itself (hee hee) and causes Stormwatch Headquarters to explode! That's the end of this issue but it leads to a mini-crossover in Stormwatch #6, Superman #6, and Grifter #7! I hope I remember to read those issues in that order. I'm sure Superman #6 will remind me to read Stormwatch first. I hope.
