I've been trying to think who that Symkarian girl is but I can't recall that. I do recall the time he was engaged to Shalla Bal but in a double reverse, she was first revealed to be just a Latverian woman who looked like her. Then Mephisto showed up at the end to reveal to the reader that it was Shalla Bal and that she was mind wiped to think she was a Latverian woman who was brainwashed into thinking she was an imposter.
