The High Priestess of the Lord of Light met Tyrion in season six and claimed Dany was The Prince that was Promised. Though we saw the priests and priestesses of the Lord of Light were spreading the word around Meereen, we haven't seen Kinvara since.

We'd love to see Kinvara run into Melisandre at some point and have a showdown. While Kinvara believes The Prince that was Promised prophecy points to Dany, Melisandre believes it could be Jon Snow.

There's evidence for both in the books and the show, but it would be fascinating to watch these two characters discuss it in season seven.
