Arya Stark -- currently the 'GoT' G.O.A.T. -- might not get to enjoy her Winterfell triumph for long ... she's jumped to 12/1 odds as the next character to perish, after being 33/1 last week.
She's not the favorite to die next, though -- that title goes to The Mountain at 11/4, followed by Rhaegal the dragon at 4/1, The Hound at 4/1, Grey Worm at 5/1 and Bronn and Euron Greyjoy at 8/1.
Interestingly, Jaime Lannister is 16/1 to die next, after being the fave last week at 5/1.
Cersei Lannister -- who hasn't even been seen in the past 2 episodes -- will be back in action next week and is moving up as one of the favorites to sit on the Iron Throne.
She's gone from 22/1 odds to rule Westeros last week all the way to 9/1. Tyrion's odds have also drastically changed -- he's now a top-3 favorite at 5/1, behind Jon Snow at 3/1 and Sansa Stark at 9/2.
Bran -- who was the favorite to rule the Seven Kingdoms at the beginning of the season at 2/1 -- is now 8/1 along with Daenerys Targaryen and Arya.
Other popular bets to make include who, if anyone, will kill Cersei. Jaime's the favorite at 3/2 while Arya is 5/2 and Tyrion is 5/1.
The strangest twist after episode 3, though ... Samwell Tarly is gaining bets for the last character to speak in the season finale. The action suggests there could be a leak from 'GoT' insiders, and he's now the favorite at even money.
