I think Sam is more platonically in love with Frodo than Frodo is platonically in love with Sam. Sam has this devotion that goes beyond, "I'm your servant back in the Shire." It goes beyond, "You have a mission and I'm going to support you." It's very, very personal. It's all about Frodo. It's just not sexual.

And I think that what brings it into sharp relief is that Frodo is almost completely oblivious to it.
