- —Sedrick explaining Simon's fired status (src)
Sedrick acts as the rival of his twin brother Simon Masrani, and the apple of his parents' eyes. He's very cocky, but level-headed and tried to help the park by firing his brother and becoming the new manager of Jurassic World. As Claire describes it best, Sedrick and Simon are like the Indominus Twins; The always fight, they are both mischievious, arrogant, and they're twins.
Because he is the oldest twin, he was apparently the apple of his parents' eye, and always got what he want. He went to university and then became a Chairman of the board, slowly working up to top rank. Everything else about him is unknown.
Sedrick first arrived at the park telling his brother, Simon, that he is fired, and when Simon's assistant, Greg, told Sedrick to name one bad decision that Simon has made, and Sedrick proceeds to name three. Sedrick then started firing employees, because he installed a system known as the Computer Interface, or "O.O.P.S.I". He told Claire, Owen, Simon, Greg, and Dr. Wu that, with the Interface around, the park will be managed smoothly, but as that turned out to be false, she turned on Sedrick and wanted to eliminate all humans on the Island. The rest of the two episodes, he keeps fighting with his brother, and in the end, once Simon managed to stop the Indominus Twins, Sedrick apologized to Simon, and gave him his job back. In return, Simon gave Sedrick the job of managing the park's air refresheners.
