I assumed Astarion is sterile due to the vampirism so it never occured to me, he doesnt seem to be the family type anyway. Wyll and Gale seem like theyd be open to it maybe, but when Gale mentioned writing a letter to his mom I immediately got monster in law vibes for some reason. Im sure Karlach would love to be a mom though.

But the only babies I want are Halsin babies anyway.

I can just see it so vividly:

Tav, having just given birth: "Halsin, would you like to hold your son?"

Halsin, nervously taking a tiny newborn into his big strong hands, holding him skin to skin against his chest. His face flooded with emotion.

Im seriously close to just writing up a bunch of fanfiction.
