In this show, people normally can't just disappear forever, especially if they are important characters. We need confirmation of important characters deaths or fates. For example some people we haven't seen for a few seasons are about to reappear this season.
We may not see Jorah the rest of this season or even season 7. But we will see him again. Even if we have to wait till season 8 to see him. He has a part to still play in the story. And his GREYSCALE, has a part to play in the story as well, I think.
Unless you're Stannis
oh wait I forgot about Syrio and Gendry....fuk nikkas just disappear whenever.
I hope we don't have to follow Jorah though....maybe he'll just appear as one of those Stone Men down the line
