Is it possible that the biggest plot twist of King Aegon III's early reign was orchestrated by a loyal Green? Here is the ultimate theory on exactly how and why Lord Tyland Lannister—not Unwin Peake—hired a Faceless Man to assassinate Queen Jaehaera Targaryen.

The Post-Mortem Killing

Jaehaera’s tragic plunge from Maegor’s Holdfast is often blamed on Unwin Peake. However, a closer look at the timing of events in [Fire and Blood](https://awoiaf.westeros.org/index.php/Fire_%26_Blood) shows the assassination occurred after Lord Tyland Lannister died. Considering [Faceless Men](https://gameofthrones.fandom.com/wiki/Faceless_Men) take contracts that can be fulfilled long after the initial transaction, it is highly probable Tyland paid for the hit before his death, knowing the realm’s fragile peace would fracture. 

The Motive: Johanna Westerling's Ambitions

Why would a staunch Green supporter kill the last royal member of his own faction? The answer lies in the Lannister and Westerling alliance. Lady Johanna Lannister (née Westerling) and her father, Roland Westerling, held immense influence. With Jaehaera gone, the throne was open. The grand theory is that Tyland, acting on behalf of the Westerlings, had Jaehaera eliminated to make way for [Aegon III](https://awoiaf.westeros.org/index.php/Aegon_III_Targaryen) to marry into the Lannister family, securing unparalleled power for the West.

The Ultimate Ironic Betrayal

There is no greater irony in all of [Westeros](https://awoiaf.westeros.org/index.php/Westeros) than a devoted Green loyalist engineering the end of the Green line. Tyland Lannister spent the Dance of the Dragons enduring torture and mutilation to keep [Aegon II](https://awoiaf.westeros.org/index.php/Aegon_II_Targaryen) on the throne. By arranging Jaehaera's murder, he made the ultimate sacrifice for his house's legacy, intentionally striking down the last symbol of the cause he bled for.
