Things have not been what they seem. Spawn, Nyx and The Redeemer have all been playing right into Mammon's hands. Spawn and The Redeemer fight among themselves, with Spawn pinning down The Redeemer and threatening him with his own sword. Mammon reveals to Nyx that she has not only betrayed Spawn, but also been tricked into giving Mammon her connection with the Hellspawn. And it should only be a matter of time before the world finds out what Mammon plans to do with this newfound power.
