So according to the weeks ahead preview below, Melisandre and Dany meet up soon. The red witch, who last we saw had been banned from the North by Jon Snow, is at Dragonstone to recruit Dany for a higher purpose. According to Melisandre, she and “another” (presumably Jon Snow) have a role to play in the future of Westeros. This could mean they’re both connected to the Azor Ahai prophecy, along with the Prince That Was Promised. But it’s too soon to tell now. All we know is it won’t only be dragonglass that brings ice and fire together.
