(This won't follow the actual story line. This is what is going on inside my head)

After Sabre demands to know what he did with Galaxy Steve, Void transports Sabre to the Void. There, Sabre and Void both find out that Sabre is not all what he seems.
What's so different about Sabre, and what will become of this?
