I wonder how that conversation will go over?
"Yeah kids, you had three siblings a long time ago, but their mother murdered all of them." Why is he so excited to tell his hypothetical future kids about his dead ones? Like I don't think I'd disclose that information willingly to them, but he seems stoked to tell his kids-to-be about how his former children were killed. Doesn't he think that might make them afraid of their own mother if they learn mothers are capable of ending their kids' lives?
