After the hostage exchange is agreed, Troilus suggests elopement, but Cressida argues that he should not abandon Troy and that she should protect her honour. Instead, she promises to meet him within ten days. Troilus spends much of the intervening time on the city walls, sighing in the direction where Cressida has gone. No horses or sleeves, as used by Guido or Benoît, are involved in Troilus' learning of Cressida's change of heart. Instead a dream hints at what has happened, and then the truth is confirmed when a brooch – previously a gift from Troilus to Cressida – is found on Diomedes' looted clothing. In the meantime, Cressida has kept up the pretence in their correspondence that she still loves Troilus. After Cressida's betrayal is confirmed, Troilus becomes ever fiercer in battle.
