Yeah . . . the weirdest part was this flashback, where it turns out that this girl is genetically engineered (that's where her Dumbledore heritage comes from, how convenient) and James and Severus had sex to escape from Moony, or something weird like that. It's like "okay, so instead of just dragging him back down the tunnel, James, you're going to give the wolf an even stronger scent to follow. How smart."

And then of course Snape topped, but he was the one who got pregnant. EXPLAIN that to me.
