Titinius
Titinius is the play's emblem of faithful Roman friendship — a man whose loyalty to Cassius is so complete that he cannot survive it. His role in Act V is structurally crucial: his mission provides the occasion for Cassius's fatal misreading, and his suicide on returning is the act that closes Cassius's arc.

Biography
Titinius is a Roman officer and one of Cassius's most trusted companions — present through the latter half of the play as part of the republican command at Philippi. He is a figure of quiet loyalty, the kind of man who appears reliably at his general's side without demanding attention for himself, and whose importance to the play is concentrated into a single devastating sequence in Act V.
Cassius, his eyes failing, sends Titinius to ride toward some distant horsemen and report whether they are friend or foe. Cassius watches from a distance as horsemen surround Titinius — and, misreading what he sees, concludes his friend has been captured by Antony's forces. It is, in fact, Brutus's soldiers cheering a comrade. Cassius kills himself on a false reading of the situation, and Titinius returns to find his general dead.
Titinius's response is the play's most economical tragic action: he takes the garland he had brought to honour Cassius, places it on his dead friend's head, and falls on his sword. He dies with an accusation — 'O hateful Error, Melancholy's child' — directed at the misperception that killed Cassius rather than at any person. His death closes Cassius's story with a loyalty that mirrors and answers Cassius's own.
Motivation
Titinius is motivated entirely by loyalty to Cassius and the republican cause. His death is not despair but the logical conclusion of a devotion that has no content without its object.
Personality
Titinius is defined by his loyalty rather than by any individual quality — he is the kind of man whose character is most fully revealed by what he does when the person he serves is gone. His suicide is not weakness but the expression of a Roman conception of honour in which survival after such a failure of mission is itself a kind of betrayal.
