I thought this episode was great. I mean a lot of college students in their freshman year find their roommate to be almost demonic in their annoyances. My first roommate was just awful- she played Techno Hindi allllllll the time (A genre I didn't even now existed until I met her), and to make it worse it was the same three songs over and over again. She also did not seem to grasp the concept of 'turn it down'. She also used to complain about everything in the halls. Luckily for me, she decided to leave college three/four months in so I was roommateless for about a month until another girl who'd asked for a transfer got thrown in with me. And she was thankfully, lovely.
So, personal story aside, I thought this was a great and albeit-hit-you-over-the-head-with-the-message-metaphor episode to explore that. I mean you're really lucky if the first person you are roomed with you get along with.
Course my roommate didn't try and "borrow" my soul but still....
