Let's be honest: Tyrion Lannister has been a pretty bad Hand of the Queen in "Game of Thrones" Season 7. And one fan's observation makes sense out of Tyrion's failures.
Redditor volkanhto noted that Tyrion (Peter Dinklage) has had zero cups of wine so far this season. Remember, this is guy who once said, "I drink and I know things." Clearly, right now, he is not drinking and he does not know the things.
So far, Tyrion's strategy has lost them their allies from Dorne, Highgarden, and the Iron Islands; stranded the Unsullied in a cleaned-out Casterly Rock; and allowed his family to ransack the Tyrell fortune to pay back the Iron Bank. It was Daenerys' idea to fly her dragon into combat and torch the Lannister army to smithereens.
Luckily for Tyrion, he's about to glean some knowledge from the bottom of the winecup. In the teaser for Season 7, Episode 5, "Eastwatch," he's back at Dragonstone, sipping the good stuff (about 12 seconds in):
"Game of Thrones" airs Sundays at 9 p.m. on HBO.
