Loook I'm not trying to say you can manipulate Morrigan by saying nice things about Brigid...
...but... you can probably manipulate Morrigan by saying nice things about Brigid. Come on, people, I keep leaving you openings, and everyone misses them. Why do you think I relocated Brigid and gave her exact location? Remember, I don't mind if people take advantage of my characters' weaknesses, as long as it is done fairly and within character. It's the same reason why I have openly admitted that Sunny is impressionanle, or that Jessica has spectraphobia, or that Alexia has Automotonophobia.
