So, I'm doing Varys quests in order to make Dany appear in the game. Unfortunatly, I'm kinda stuck with the quest of Varys that takes me to Dorne a second time, called "The Messenger".
My task is to deliver a message to Ellaria Sand, in the quest log it is mentioned that I can find her in the village The Water Gardens.
The problem here was that I didn't find her. So I went and searched for her and found her in the castle Planky Town. But whenever I talk to her she is just a regular female lady character, there isn't a option for finishing the quest.

Can someone help me with that?
