From what I remember last night, this seems to follow the events:
1. Brock gets taken to the agency's hospital/experiment bin, and has Helper's head stuck to his chest.
2. Number 24 is dead and 21 is trying to figure out what to do to bring him back.
3. Neo-nazis/poser Nazis demand that Dr. Venture revive Hitler with the dog
4. Sergeant Hatred is the new "bodyguard" of the family and Hank misses Brock [obviously].
5. Brock goes to the doctor who operated his old mentor and gets Helper's face out... plus the doctor makes him fat and puts a beard on him so he can hide better.
6. Hitler is the dog, so Dean loves Hitler and Hitler loves him.
7. Brock sends Helper's head back through mail, Dr Venture eventually reconstructs him into the monster thing.
8. Brock infiltrates the women team of Molotov Cocktease and spies on her plus his old mentor.
9. He fights a spy from the egyptian-like team and eventually gets captured by them.
10. After a couple of minutes, it is revealed his old mentor did the hermaphrodyte transformation as to infiltrate Molotov's team, and that HE is the leader of the egyptian-like team.
11. Dr. Orpheus fights the rebuilt Helper [can't remember why]. His attack kills the Nazis as well.
12. Hank is attacked by the Hitler dog, when all of a sudden Brock and his team appear and kill the dog.
I don't know where number 21 taking the X-1 and bringing his Larping buddies fits in the story line.
