Sextus, meanwhile, is at the Capitol, which he and his friends are going to burn down. Sextus cannot think what is the right thing to do. The other characters (except Titus) enter and are horrified to see the burning Capitol. Sextus comes in again and says that he saw Titus being killed, but Vitellia stops him giving away the fact that he was the killer. The others lament Titus in a slow, sad end to Act I.
