Antony asks (and basically forces) his most loyal soldier to kill him, because, you know, Antony is a pathetic wuss and he cannot do it himself (because of all the honor crap, I suppose). But the soldier cannot do it. Instead he kills himself. And just FYI, I liked the soldier guy.
Someone should just have told him "It´s so not worth it to die for Antony. He is an incompetent idiot."
