5. Osmund Kettleblack - 150 Mentions

Political machinations are also a huge part of the ongoing book storylines in King's Landing, as we've already seen with Cersei Lannister's interactions with Taena Merryweather. The Queen Mother also has extensive dealings with the Kettleblacks, Osmund, Osfryd and Osney, three brothers of questionable repute. Cersei, Tyrion and Littlefinger all believe the trio to be working for them at first as they attempt to build up their own bases of sellswords and spies, making their actions hard to follow at times.

All three eventually become Cersei's creatures, as Osmund becomes a highly questionable appointment to the Kingsguard, Osfryd becomes the commander of the City Watch and Osney becomes caught up in her various schemes, assassinating a High Septon and then attempting to seduce Margaery Tyrell in a bid to discredit her. All three bed Cersei, and all three end up arrested when her schemes go awry and she ends up a prisoner of the Faith.

Though the trio are interchangeable given their near-identical names and roles, a composite of the three would've been a decent addition to the King's Landing background, adding depth to the Kingsguard and strengthening the Faith's on-screen case against Cersei, which is built almost solely on the testimony of her cousin Lancel.
