There was no end to Anu's torment of Jeanne, intentionally or otherwise. His existence would only become more of a plague against those who found themselves connected, until he was dealt with properly. Sadly, this group in particular would be dealing with him far more than others. Their individual journeys had not been pleasant ones, and their combined journey would have a similar amount of turmoil. While the Nexus mulled over these facts, Jeanne carried on about having children with one's friends. Charlemagne was astounded that he'd even be called a friend at this point, but the Nexus had more to say yet again. "It's not a normal sort of kid, really. I should also say, I'm giving you an option. You don't have to do this; I could break the connection by cycling that child back into the world. Instead, I figured you'd rather avoid the option that'll have people worrying forever. The choice is still yours," he declared. To ensure the decision of both parties was a certain one, he even chose to give proper details ─ spoilers, even.
"Alright, so listen. I'm gonna give you guys some spoilers before I do this thing. No kid? Anu births a Child of the Nexus into the world, Anu gains a connection to me that's as strong as yours. There are some other, deeper spoilers which make that a terrible idea. Kid? Another innocent girl out there will still be taken advantage of, but the whole world won't suffer much for it. Third alternative where I cycle the kid back through the grail system? Same as the last, but..." He took pause there, looking toward Jeanne specifically. "You're missing a root. That's one of the things I can't see entirely, but you run the risk of becoming a Beast. By now, I think you know what that is. You should also know who makes the majority of the Beast-stopping list," he concluded. Recently, Jeanne should have learned about Beasts and the like. As for those who could stop them, two were among her precious family members, and few others were comrades including Charlemagne himself. If Jeanne d'Arc became a Beast, she'd be one of great power that required multiple of those people to end her. "Going against Fate is a dangerous thing. I know it's not your fault that either of you ended up on this path, and I'll do what I can, when I can, to make amends for that. But this time... I'll leave the choice to you. As another spoiler, I can tell you the kid would be a precious light in all of your lives."
With that long speech out of the way, Charlemagne finished drinking from the grail. Sakura refrained from further questioning another human thought process, so he didn't have to worry about that any longer. Instead, his concern went to the matter at hand about... somehow having a child with the blackened Jeanne d'Arc. It didn't seem to be something that required intercourse, based on the Nexus's earlier words. Moreover, if it kept Jeanne from additional unnecessary tribulations, well... he could accept the option despite how strange it was. He'd already gone down the proverbial rabbit hole anyway, so why not? "These life options aren't getting any less weird either. At this point, I'll do whatever helps the most. I've done enough fence-sitting for one millennium. Where's the fourth option where we just undo most of Aincrad, though?" he griped.
