I'm not worried about that, Hacob will get the blade. Platypus will be there, and he just finished the most exhilerating fight of his life. Are you sure you want to fight him? He just drew a Narrator who has been Narrating for probably 10x how long he has, and he learned from that fight.
Hacob will return if the blade does. That is just a fact of the way they were banished. Unless Desolation manages to destroy the Plotblade (which we've determined is probably impossible unless Plot came back) Hacob will be back when Nohr Maul is. Wait, the point of Suddenly, Pineapples' ability is to banish things for a near infinite amount of time and you're bringing it back in 10 pages? I don't think that is canonically possible. Desolation might have gotten closer to returning from the dark energy, but that doesn't mean the Nohr Maul did.
Aight.
Platypus appeared, floating in the air, still glowing with power, but with Vengeance in hand, rather than absorbed. "Just what do you think you're doing? I haven't met you, and I don't trust that black goo."
