Et tu, Brute?”
(Julius Caesar, Act 3, Scene 1)

This quote is in Latin and loosely translates as ‘Even you, Brutus?’ In the play, these are Caesar’s last words when he is killed by the conspirators. Their leader, Brutus, is a long-time friend of Caesar, who saw the danger of Caesar’s ambitions and felt he needed to be stopped. This quote lives in our memory because it symbolizes ultimate betrayal by a trusted and beloved friend.
