Explanation:

To determine where Brutus believes the weak side of the battle is, we analyze his lines: "But cold demeanour in Octavius' wing, And sudden push gives them the overthrow." This shows he thinks Octavius' wing (side) has a cold demeanour and a sudden push can defeat them, meaning he believes Octavius’s side is the weak one.
