I mean, the whole appeal of Elthara was that she was obsessed with having babies with PC. So to suddenly have half of her content be about her getting bred by our companions.
It really should have went into more interactions with PC, her and her child. Or more focus on her pregnant state.
Also, on more personal note, it kind of sucks to know that your bedicked companions are more than happy to knock up someone with just drop of a hat. Really makes my vagina champ feel valued and treasured, you know?
