3) Loras Tyrell
Loras currently awaits trial after being accused of fornicating with Renly Baratheon, making him the third major Game of Thrones character who the Faith Militant hopes to take down. They can’t all make it out scott free, right? Plus, a conflict between the Lannisters and the Tyrells has been brewing for years, and the death of Loras would be just the catalyst the show needs in order to send King’s Landing into complete and utter chaos.
Loras’ fate would motivate Margaery to go after Cersei, and perhaps a Tyrell vs. Lannister war would begin. That would be on top of the Martell vs. Lannister war that is a virtual certainty after Myrcella’s assassination.
From a production standpoint, Finn Jones was recently cast as the titular character in Netflix’s Iron Fist, which is quite a large commitment. It’s possible he was able to balance both shows in his schedule, as Loras does not appear in every episode, but it’s curious that the actor landed a huge television role during the very same season that his Game of Thrones character is in peril.
