Rainey, you're giving Willie too much credit there. Even though you, as the viewer, have the chance to sit there and reason what would have been right or wrong to do, Willie was thinking on his toes. And even though I love the guy, he wasn't always the brightest bulb in the box. He was thinking with his heart, not his head, in this case. For all he knew, Barnabas was about to use the one he loved in an (imo) inane experiment which in effect could very well have cost her her life. So, he panicked! He did the only thing he felt he could do in this situation and stole her away. Although the mausoleums secret room was the last place anyone should have taken her who was trying their damndest to keep her memories from resurfacing, Willie merely thought of it as the best hiding place to keep her away from Barnabas. His fears had him constantly paranoid, so high-tailing it out of town was certainly out of the question. He was too afraid Barnabas would track them down.
The issue wasn't whether Barn was still a vampire or not. It was that Willie felt that Maggie's life was threatened. Even though he did the wrong thing in taking her to the mausoleum, that was still a noble gesture, imo.
Maggie could have told the police. Willie also could have gone with her and reported all the other crimes Barn committed. Why didn't he let her? Because Barnabas was his "friend". As he told Maggie, "Friends are very important to me." I think it's b/c he didn't have anyone he could call a true friend. In his minds eye, I think he fancied thinking that he and Barnabas had grown close. In essense, he was making excuses for his tormentor/abuser. Nothing says it better than "stockholm's syndrome". Look it up. A friend mentioned that a while back on the Willie Loomis List and I think it fits Willie to a "t".
I do totally agree, though, that they should have dragged this on a bit more. This was, after all, what started DS's upward climb to greater recognition, so why just drop it? I guess b/c the writers didn't want any one of the main good characters to dislike Barnabas. Maybe they felt it would ruin the image they were trying to present to the audience of him. Bad writing, I tell ya. Never much cared for the way they handled this, myself.
And what happened during this so called more prominent story with Eve? I wouldn't know. I couldn't keep my finger off the fast-forward button. ~DJ
