Undeclared TVD - 4.01 Growing Pains

We did it, y'all! We have arrived in Season 4, with all of its Elena-as-a-vampire glory despite Bonnie almost killing herself and Stefan's uncharacteristic Pollyanna hopefulness. What does this new development mean for her recent decision to pick Stefan over Damon now that she has remembered what he compelled her to forget? How will it affect her friends, and her brother? And what is the deal with that annoying Pastor going on a crusade and then blowing himself and the new Town Council up?
