However, just before his final scene on the polarising - and gruesome - HBO drama, it appeared to have grown back!
As Jamie wrapped his arms around Cersei Lannister, viewers saw his hand emerge from the side of her waist.
"Oops, looks like the Starbucks mishap was only the top of the iceberg. Jaime's hand magically healed in Episode 5," wrote fan Toni via Twitter, alongside a screenshot of the scene with his hand clearly circled.

Toni reminded fans that just a week ago, a Starbucks coffee cup was seen resting on a table during another intense scene.
Now, other viewers are expressing their shock over the blunder.
"Nice observation, sad error," wrote one, while another joked, "I couldn't see it through my tears!"
