Cassius questions Brutus

I was with brutus after Caesar left, being warned of the ides of March, and I asked him if he wanted to go see how the race was going. Brutus said that he is not competitive like Antony and said no.  So Brutus and I continued talking and I realized that he was not acting like himself lately. I was confused and curious to what was wrong with him so I came out and asked him.  Brutus said that he has been troubled by his own thoughts and inner conflicts.
Brutus and I continued communicating and we heard trumpets and loud shouts.  Brutus questioned what was going on and feared that they made Caesar king.  He said that he does not want him to be king.
