Tywin is bathed in bright light while Cersei is in the dark shadows. Tywin takes Tommen away from Cersei, away from the darkness and up the stairs into the light. This is probably one of the only instances in the series where Tywin is "in the light" compared to another character. He is also acting Hand of the King . Tywin was shrewd. He would have had the boy set right or put down. He likely would have had some ploy to make Joffrey better that would have involved the memory of Robert's prime. Joffrey wanted nothing more than Robert's approval, and to use that against Joffrey seems right up Tywin's alley. Twog9Z. Tommen Baratheon (Callum Wharry) HBO Cersei and Jaime Lannister's second-born son, Tommen Baratheon, was played by Callum Wharry for the first two seasons of Game of Thrones . They are of First Men origin through the female line, though they follow neither the Old Gods nor the customs of the heritage anymore since Andal adventurers married into the family hundreds of years ago. The Lannisters are powerful and controlling, and completely merciless to those they view as weak. They are effectively the royal house and So, after Bobby B died and the throne went to Joffrey, he was crowned and did basically everything as he liked. But, when Joffrey died and the throne went to Tommen, Cersei and the counsel rule in his behalf. Considering both of them were kids, (Joffrey was 12y/o and Tommen was 8), why didn't Cersei stopped all irresponsible acts in Joffrey's Cersei Lannister entered the great hall to find a crowd gathered to hear an announcement from Tommen. Tommen declared that the trials of Loras Tyrell and Cersei would be held on the first day of the festival of the Mother. He went on to say that trial by combat was to be made illegal and that both would stand a formal trial. It's the Baratheon name that has claim to the throne, not the Lannister name. So, when Robert died, his oldest "son" Joffrey took the thronethen Tommen after Joffrey died. After Tommen's death, the claim to the throne goes back up to Cersei since she is the only surviving Baratheon from Robert's direct line. Although her family plays one of the largest roles in the series, the eventually recast Myrcella Baratheon played the smallest part in the Baratheon/Lannister family. Cersei’s (and Jaime’s) daughter Myrcella Baratheon was largely a background character in seasons 1 and 2 of Game of Thrones , who was played by child actress Aimee Richardson
