Game of Thrones Season 6 Episode 4: What did the High Sparrow tell Tommen in secret that he repeated to Cersei?

In "Game of Thrones" Season 6 Episode 4, the exact words of the secret conversation between the High Sparrow and Tommen are not explicitly revealed in the show, leading to various fan theories. Here are some of the prominent theories:

Involvement in Joffrey's Murder

One of the most popular theories is that the High Sparrow told Tommen about the Tyrells' involvement in Joffrey's murder. This theory suggests that this revelation was what upset Tommen and prompted Cersei to take action against the Tyrells and the Faith Militant. This is supported by the emotional reaction of Tommen and the subsequent actions of Cersei to broker a deal with the Tyrells, potentially as a ruse to create unrest and blame the Tyrells23.

Cersei's Trial and Margaery's Confession

Another theory proposes that the High Sparrow might have informed Tommen that Margaery would soon be forced to confess her sins, which could have implications for Cersei's own trial. This could explain why Cersei was so keen to prevent Margaery from undergoing a walk of atonement and why she sought to use this information to her advantage1.

Influence Over Tommen

Some fans speculate that the High Sparrow's words might be influencing Tommen's beliefs, potentially making him more sympathetic to the Faith Militant's cause. This could worry Cersei, as she might fear losing her son's loyalty and support1.

Despite these theories, the show itself does not provide a clear answer to what the High Sparrow said to Tommen, leaving the interpretation open to speculation.
