We will meet Loial at the next episode. But this is obvious from the casting for the episode.
Less obvious prediction: "We will meet Elyas." ( because for this season it's either this episode or never)
I think the next episode will be Logain heavy (Logain is the "The Dragon Reborn" in the title) and it'd explain a lot more about what is "The Dragon Reborn" . Perhaps even Logain will escape at the end of the episode...
