I disagree with Tara not being Willows type... Yes, I think she started to get more interresting only when they were fighting about Magicks.... But that was because Tara was finally TRULY hurt by Willow, and thus showing how much love she had for her, like she said in All The Way... The only reason she wasnt sitting back and letting Willow do her Magicks was because she loved her so much...
When I first watched Season 4, and their earlier encounters, I thought myself that they didn't mesh too well... It just seemed like they were both too quiet... There would be no initiative... But when I watched closely, and saw that there was MUCH more to the two than sexual needs... It showed me that there was something more than I'd seen before... Their relationship was made to seem different than anyone elses, as they were primarily drawn together by the Magicks... Watch the episode Who Are You from Season 4... And pay particular attention to the spell that Tara and Willow cast in order to see what's wrong with Buffy... Then tell me that Tara and Willow weren't meant for each other 😀
