Back at Gilbert Gables, Elena joins Alaric and Jenna in the kitchen. Jenna's on the phone, saying, "Of course, I understand." She then tells Elena the call is for her, but doesn't answer when Elena wants to know who it is. Oh no. I saw the previews for this episode. I know what call this is, and now I know the implications -- Jenna's enthralled. While Katherine chides Elena about sneaking around with Stefan, Jenna fades into the background, but we get a warning shot of her slicing bread with a ginormous knife. Katherine reveals that she stole Jenna's vervain perfume and got her off the vervain tea, and so far she's been as awesome at spying as she is crappy at guarding her charges. As Katherine crows, "So, when I suggested the world would be a much better place if she were to just..." Elena drops the phone and yells, "Jenna, no!" Jenna lifts the knife up in front of herself and aims it at her own gut. Alaric calls out to Jenna as he rushes toward her, but they're both too late, and not nearly as compelling as KaKa, because JENNA PLUNGES A KNIFE INTO HER OWN GUT! Even though Elena's no longer holding the phone, Katherine smiles as she listens to the hubbub at Gilbert Gables. "Well, you get the idea." As Elena and Alaric huddle over Jenna and I rock back and forth in shock, we cut to commercial.
Hospital Waiting Area: When the Gilbert kids learn their beloved auntie/crap guardian will live, Jeremy promises Elena that Katherine's going to pay. I know he thinks this is comforting, but I'm sure it frightens Elena even more on his behalf. I'm studiously not mentioning the chemistry between these two actors, because they play siblings.
