You have to drink the unknown potion and experienced its three time. After that, fight DR Swan and prolong the fight until you are forced to gaze at her feet three times. Lose to that and you should be done for now. In this fight you don't need to drink the poison.I am stuck. I have extreme dependency on ms swans and I have won the fight and lost the fight in all the ways I can imagine. How are you supposed to know when you have seen everything and if there is something I have to do please tell me. I wish this was less tedious so I didn't have to ask WTF I'm supposed to do or if I'm done.
