The walkthrough mentions it ("In fact, he can even continue to visit her afterwards but he'll need to bring her a present..."), but I think it was made a quest after that was written. You get the quest if you ask for sex after she announces pregnancy. Edgar's shop has something suitable (it's expensive).I went back to check on the dragon (Vixenatrix?) and got another quest - "Bring the Lady a Gift." This quest doesn't show up in the walkthrough. Did I get the quest too early? or did I just miss it in the walkthrough? Thanks.
FYI Vixenatrix will be receiving an update allowing her to lay her egg, like how the next update adds pregnancy & birth for Beth. We don't know how soon Vix's update will be, but it will happen.
