what's important to remember about the 'we didn't even kiss' unsent text is that shane is not mad at ILYA about the sex they had. he leapt readily into the sex, slutty arch that ensnared millions on display etc.
no, shane's in the elevator, biting his lips red, wishing it was ilya's spit he was tasting and he is mad at HIMSELF for wanting to be kissed, for wanting MORE and recognizes (by ilya setting the tone of the sex as competitive -- not personal, by his own estimation of their relationship) that what sex they SHOULD/MUST be having according to the twin torture nexus is not sex where they kiss each other like they need each other's mouth to breathe. 'we didn't even kiss' is 'i, shane hollander, once again want something i cannot have, because that is what i do, lug around a want so ugly and so loud and so mighty that i fear people can read it at a glance across 200 ft of cold, powdery ice.'
