If you happened to watch this week's episode of 'Game of Thrones', it all looked pretty conclusive that Cersei and Jamie Lannister both met their ends when the Red Keep of King's Landing fell down on top of them.

Whether or not it seemed like a fitting end is open for debate, but that ending appeared to be pretty conclusive - or was it? There's now a growing theory that Jamie Lannister may have, in fact, survived last week's episode and will reappear in the final episode this coming Monday.

The evidence is, admittedly, thin at best but it's enough to give you pause. Basically, it boils down to two things. First, we need to look at the social media of both Nikolaj Coster-Waldau and Lena Headey, and all of the cast of 'Game of Thrones'. None of them mentioned the fact that this week's episode was their last, which is a little strange in the scheme of things.

The next, more pointed one however, comes from Entertainment Weekly. The US outlet has been conducting exit interviews with cast as they died off in each episode this season. For example, they ran an interview with Pilou Asbaek, who played Euron Greyjoy. Another interview went out with Lena Headey, who played Cersei Lannister.

However, no interview - as of writing - has gone out with Nikolaj Coster-Waldau. When asked about this, EW's James Hibberd posted this decidedly cryptic tweet.

Just to make it even more intriguing, someone posted an article where he discussed being present at the final episode's filming and pointing out that characters he didn't expect to see there being present on set. So, does all this equate to Jamie Lannister being alive? To be honest, 'Game of Thrones' has killed off people for shock value - so bringing someone back for the same effect wouldn't be outside the realms of possibility.
