   Summary

   Samuel Hayden has been through a lot: after the time-y why-me shitty shenanigans that fighting Hell's Horde results in, he was sure he paid for his sins and that everything was truly over. Argent Energy has been rendered useless, and though this new universe suffers its own plethora of troubles, he's found it easy to endure.

   However, leave it to fucking mortals to be too curious and go touching things they shouldn't. Now faced with (forcibly) reuniting with his ex-ally (or whatever the hell their relationship status had been), the immortal's troubles have increased with the addition of an unwanted soul that the Slayer insists will be their shared son! Is he insane!?

   Or maybe not; there's something inherently sad and lonely about the infamous green SPARTAN-II, and make no mistake, it's going to generate questions as to what it means to be human... much less, what it means to live without violence.

   Doom runs in this family, the lack of blood relation be damned.
