How did Tyrion Know...
I just finished watching Eastwatch for the second time, and I have come to wonder this..
How did Tyrion and all who serve Dany know that Jaime survived the Dothraki/Drogon attack?
Without hesitation, Tyrion suggested to pay Jaime a visit at the Red Keep, without thinking that perhaps he is at the bottom of Challenger Deep. Did I miss something? Let me know what do you guys think.
