OK, we haven't had many major deaths in Julius Caesar so far. Caesar, obviously, and Cinna the poet, but no other on-stage deaths.
Well THAT'S ABOUT TO CHANGE.
This is Titinius. He previously appeared in the tent scene, where he said, and I quote, "Goodnight, Lord Brutus", a line which he had to share with Messala. He's famous for being a total cipher of a character who suddenly becomes incredibly important to the plot.
He is also responsible for giving birth to the timeless phrase "Who the **** is Titinius?"
