Neelix was actually incapable of rubbing her feet until her tongue swelled and what is the matter of letting a robot doctor do it? I am sticking with the fact that Neelix could never really satisfy Kes's sexual needs. So in 'Darkling' (2/3) through Season 3 Kes falls in love with somebody planetside and she wants to experience with him in paradise. In several more episodes she is gone. Forever.
