Answer:
The tone in this exchange between Brutus and Cassius is that of a sincere, serious tone.
Explanation:
William Shakespeare's "The Tragedy of Julius Caesar" revolves around the murder of Caesar and the eventual fight for power over Rome. The theme of loyalty, friendship and even respect all comes in the play.
The given exchange between Brutus and Cassius, the two perpetrators of Caesar's death is from Act V scene i. This scene is the final scene of the war where the two warring sides meet before the final war. After meeting with Octavius and Antony, Brutus and Cassius talk about the war and then said their farewells,
<em>"whether we shall meet again I know not.
</em>
<em>Therefore our everlasting farewell take.
</em>
<em>Forever and forever farewell, Cassius.
</em>
<em>If we do meet again, why, we shall smile.
</em>
<em>If not, why then this parting was well made."</em>
Cassius also bids his <em>"forever and forever farewell"</em>, thus ending the sincere yet serious conversation of the two allies. This scene shows the sincerity of the two friends, unsure of whether they will survive the war or not.
