Achilles might be a good papa to the family, but he was also a killer, and he never forgives.Poke knew that, though. Bean warned her, and she knew it, but she chose Achilles for their papa anyway. Chose him and then died for it. She was like that Jesus that Helga preached about in her kitchen while they ate. She died for her people. And Achilles, he was like God. He made people pay for their sins no matter what they did.The important thing is, stay on the good side of God. That's what Helga teaches, isn't it? Stay right with God.I'll stay right with Achilles. I'll honor my papa, that's for sure, so I can stay alive until I'm old enough to go out on my own.
