But when her final child, Tommen, committed suicide after realizing that Margaery was killed by his mother in the explosion of the Great Sept, Cersei's reaction was truly chilling. After seeing her child's body, she coldly ordered Qyburn to burn it and to spread the ashes over the remains of the Sept.
Cersei first mentioned her pregnancy to Jaime (Nikolaj Coster-Waldau) in the fifth episode of Season 7, and later told Tyrion (Peter Dinklage) that she was carrying Jaime's baby.
