Why does Artemidorus push aside the Soothsayer in Act III ?

He is rushing to get to Caesar so that he can fight off the conspirators and save Caesar.

He thinks that the Soothsayer is one of the men who is planning to murder Caesar.

He believes that the Soothsayer is a fool who does not have the ability to predict future events.

He wants to reach Caesar before the conspirators do so that he can warn Caesar of their plan.
