MACBETH N' ME)

What i think will be interesting about the play is how is the 2 assassin that
 killed  Banquo but not  his young son, Fleance because he escapes and the king hired a 3 assasin two kill the other 2 assassin but what im more curious about is if fleance is going to die or tells someone about what happe. When 
Banquo got murder
