Another odd thing about watching 3-4 episodes a night of 5 1/2 seasons of a tv show is watching the actors get older so quickly. Especially with actors who started the show as young as these guys, and who have changed physically quite dramatically. I could really understand how tired Dean and Sam were by the end of season 5! I haven't got addicted to a TV show in this way in years.

This has also been my introduction to the world of fanfiction, which is itself fascinating!
