the datamine has shown tags and conditions for pregnancy known about=player not the father.
Also the timeline of the game, just logistically the player being involved doesn't really work unless you long rest ALOT. I really hope that plotline comes back as so much of her character is tied to what her mother did to her, and what Orin did to her and like, if somehow Orin could be the father? like shapeshifter, not human? idk it'd have thematic resonance? Like not a redemption arc but a coming-to-peace-with arc for a Vengence Oath paladin could be, brilliant, ending with committing not to continue the chain of her house and raise the child with you in love and kindness while still being evil, because it benefits her for her child not to suffer like she did. It'd be a unique story? idk
But I'd be cool with not including it especially as the game doesn't have a sizeable timeskip for baby to happen in?
For a idk, 1 year later DLC adventure or something it could be awesome but I don't see how it fits in to a story which is about a mad rush across a quite small amount of geography to stop an imminent threat?
