Griff aka Jon Connington aka Mad King Aerys's exiled hand laments losing Tyrion. So Tyrion did not get away. Haldon came back without him and has been in the doghouse ever since.
Haldon buys some horses and they all ride off to meet the Golden Company. We learn that Connington was second in command there when Varys came up with the ploy of pretending to steal stuff from the company to be exiled again to raise Aegon in secret. The new commander of the company, Homeless Harry Strickland is mainly worried about his feet and seems to be avoiding battles. But he's already told everyone about Young Griff's secret identity.
Everyone is dismayed that Dany is just loafing about in Meereen, which is a bit far away. Young Aegon comes up with the oh-so-original idea of ignoring her, going to Dorne, and declaring himself. Their main worry is that Cersei Lannister is powerful and has lots of friends. Ha ha. The Golden Company bigwigs go for the idea anyway. Connington is impressed with Aegon's ability to persuade and come up with cool ideas. Plus it suits him since he is in a bit of rush now that he's caught Greyscale and will be a stone man and only has a few years to live. Ouch.
