My scenes (Act III Scene I and III) paraphrased

I am the second murder in both of the two acts. My lines are always very short. The first and the second murder get a command form Macbeth to kill Banquo and his son Fleance. And they accept with plesure. At the third act, there are three murders, and Macbeth hired another murder to help them. They killed Banquo but not Fleance who escapes.
