Tommen Baratheon is legally the son of Cersei and Robert Baratheon; however, his actual parentage is an incestuous one. His mother is, in fact, Queen Cersei, although his father is her twin brother, Jamie. Tommen Baratheon is the heir to the throne once Joffrey comes into rule. Tommen is played by Callum Wharry and Dean-Charles Chapman.
Once Joffrey is dead, Tommen steps up to rule, although he is too young to rule in his own right. Tommen Baratheon receives the titles of Lord of the Seven Kingdoms as well as the King of the Andals and the First Men. Tommen cannot yet take the title of Protector of the Realm because he is too young, but once he comes of age he will.
Tommen is much less abrasive than Joffrey ever was, because Joffrey bullied him when they were both children. The new king is more passive and gentle than Joffrey, which is a pleasant change from the brutal tyrant that Joffrey was. Tyrion also gets along much better with Tommen and the young man often seeks Tyrion’s guidance. Tommen has a lot of respect for Tyrion, always looking to him for advice and he adored Tyrion as a child, always laughing at his jokes.
The young king also is almost immediately engaged to Margaery. They bond over the fact that they are both glad to be rid of Joffrey and a friendship blooms. Unfortunately, Tommen’s relationship with Tyrion is not as stable as Tywin manipulates Tommen. Tommen, as he is a child, is very easily manipulated, and it only takes a few words from Tywin to change his thoughts.
Tommen’s character in Game of Thrones is easy going and calm in regards to his crowning. He sits on the throne as if he was born to, as opposed to Joffrey, who took advantage of the throne.
The character of Tommen is also restricted by his mother, Cersei, as she places an excessive amount of guards at his door at night. His actual father, Jamie, deems this a bit much, but Cersei does not listen to him. This tension between his mother and father and the incestuous relationship does not seem to have affected Tommen’s blood nearly as much as Joffrey’s.
To conclude Tommen’s character, one can say that he is a likeable child. He is a ruler that deems justice, holiness, strength, and wisdom important to a king, which is comforting. It is especially comforting when the audience was so used to Joffrey going crossbow happy. Perhaps the Game of Thrones will get a little less manic with Tommen on the throne.
