Hey, uh, not sure if anyone has pointed it out yet, but given how the Starling Bad Ending was set SPECIFICALLY 18 Months after the game, a VERY SPECIFIC amount of time if you ask me, something tells me at least some of the female characters in the game are already pregnant (9 months), meaning Hunter had to wait longer to get them pregnant again (9 Months again, hence 18).
Game doesn't specify which ones, but the women being pregnant and recently abandoned by the MC would make them a cocktail of emotions that would make them easy prey of Hunter.
