TBH, I never even bothered considered that. The trope "Achilles In His Tent" refers to Achilles being all mopey-mopey-I-will-not-help-I-will-ask-my-mother-to-make-Zeus-curse-my-men-until-they-realize-they-need-me and only coming out once Patroclus, his best friend/lover, was killed. In the same was, Clarisse refused to help in TLO because she was all bitter and grudge-holding and such. :P
