Many Game of Thrones fans were disappointed when Beric Dondarrion, leader of the Brotherhood Without Banners, returned to the show on Sunday night's episode. It was highly believed that Lady Stoneheart, the resurrected Catelyn Stark, would finally be appearing on the show, since she becomes the leader of the Brotherhood, replacing Beric. But now that Beric is back, it seems unlikely that this will happen. Still, some fans hold out hope that not only will Lady Stoneheart show up on Game of Thrones, but the Hound will also meet her.
Fans first became hopeful of a Lady Stoneheart appearance when Lem Lemoncloak, a rogue member of the Brotherhood, showed up and attacked the peaceful group the Hound was hanging out with. Unfortunately, it seems that Lem wasn't actually working with Lady Stoneheart, as he was in the books, and Beric is still leading the Brotherhood. In the books, Beric sacrifices his life to reanimate Catelynn's corpse after the Red Wedding. Beric still being alive on the show seems to close the deal for Lady Stoneheart. It's been far too long since the Red Wedding for Catelyn to be revived now, so if Beric hasn't done it yet, it probably won't be happening at all.
However, if Lady Stoneheart was still going to show up in some way, it seems most likely that it would be through the Brotherhood's help and the Hound would be there. The Hound will probably stick with the Brotherhood, mainly because he doesn't really have any other plans right now, and only Beric, Melisandre — who's helping Jon at the moment — or another Red Priestess, have the ability to bring back Catelyn.
Even so, the odds of Lady Stoneheart making an appearance are very slim despite how much fans desperately want to see her on the show. The showrunners of Game of Thrones definitely did a bait and switch showing the Freys again and all the mentions about Catelyn this season. Unfortunately it seems we may never know what could've been an interesting face-off or friendship between Lady Stoneheart and the Hound.
Then again, who knows? If Jon could come back from the dead and Benjen could return once again, who's to say Lady Stoneheart won't still make an appearance? Maybe we shouldn't lose all hope just yet.
