Try in the evening, right of the podium
Idk, i went there and i even found a walkthrough video on youtube where it shows where she should be (right infront of 1st statue from the left) but she is not there, i think i glitched it. I can't remember exactly but i think i used the teleport home power while being in the special area from her quest, maybe that glitched it? I don't know how to fix it though.
