I'm afraid I have to disagree: the rage displayed by Achilles is in itself a clear hint of a closer relation, indicative of jealousy, as is the subsequent ride of Achilles with Hektor's body attached to his chariot. (And I am aware both of the vengeance motif in mythical stories and the fame of Achilles' raging character.) Also, the ancient Greeks were no freaks about their homosexual relationships, unlike the later Romans - and Greeks.
