I don't read mind. If you need help, give more info. Do you play with mod? How about posting a screenshot of you quest log? Where are you in other questline? Or post a save?
Or answer my last question which is WHAT WAS THE LAST QUEST YOU DONE FOR HER?
Or read the WT which are inluded in the walkthrought folder.
When Erevi is full term (20 days) and in bed, Bolan will be there when you enter.
Once she gives birth go to the stables and ask Beth for a date then check the well but don't go down.
Back to Erevi and ask for summon spell, back to Beth and go on a date.
Back again to the well and rescue Lliandra.
Back to Erevi to continue the quests.
