the ring didn't work because a human (the sherrif) killed jeremy, not a supernatural being, which is what that ring protects jeremy from :P And omgsh jeremy can see dead ppl now?! there's no way anna or vicki are alive so yeah! WOW! And Stefan's gonna be off with Klaus for a while, so that'll leave time for 'Delena' to possible develop?
And also, Klaus is such a rat to his brother who he 'gave his word to' to show him where their family were. BUT if elijah did kill klaus damon would have died so ARGH! ;D
