What Happens to Antillus?

Plutarch says that he is an attendant of lucius pimius, the consul. So it gives him a direct relationship to the consul, which could make him a target. And what happens to antillus is that he's just in the wrong place at the wrong time. In apian, saw gaius in a disturbed state and implored him to spare his country. Gracchus became still more agitated and fearful, like a criminal caught in the act. One of the party, without any signal having been made or any command given, but judging simply from the sharpness of gracchus look at antillus, drew his dagger and killed Antillus.
