 Parmeno reveals to Chaerea that the girl he is chasing is the gift of the soldier to Thais, and that he himself is supposed to deliver a eunuch to Thais's house for Phaedria (one of Phaedria's gifts).Based on a joking suggestion by Parmeno, Chaerea decides to substitute himself for the eunuch in order to get into Thais's house and he forces Parmeno to cooperate.Since he has been away on military service, Thais and her household staff do not know his face.
