I'm glad the DVD editions come with the Squiggy commentary. Makes the episodes twice as fun to watch. Now, I wonder if some time ion the future, there'll be some sort of director's cut edition...with behind the scenes commentary by Baggins himself!
Now, as for my advice MB (weren't those the initials givin to Major Barcalow from years back?), it's perfectly normal to feel love for someone, and have no sexual attraction to them what so ever. It comes a lot of the time from interacting with someone on a close level for a long period of time. On the road, it was just the two of you, so of course your friendship is going to grow, and you'll be accustomed to the other person being there. I've found that similar feelings (although no where near as severe as you describe), occur in myself during and after a stage production, or a big choir concert. It's just a matter of how close you feel to those around you. If I act in a scene with another person, regardless of sex, and we've been through that scene dozens of times, a certain intimacy develops. I know I can trust the other person to carry on if I flub a line or something, and they place the same trust in me. You depend on one another. Now, I've never had the urge to sleep with any of my fellow thespians, but I quite a few of them have found a place in my heart. They're fantastic people, and are some of those closest to me, with all the trust that's been built up. I suspect a similar thing is happening to you, with Thames.
If you do feel a sexual attraction to him, well, that's fine too, but before you do anything that could endanger your friendship with him, make sure that it's worth it. I've become heavily attracted to several female friends, but only on occasion have I acted on those feelings, for the good of our relationship. Sometimes, things are better left unsaid and not acted-upon. Am I making sense?
(Yes, I understand the traditional response to an MB thread is something sarcastic, and witty, but I actually wanted to pipe in the genuine advice before my sense of humor got the better of me)
