I wondered if the Tara stuff might lead them to the cure. But now I don't know what it's about! It had better be important though. If they are wasting time on Lettie May, who hasn't been an integral character through the series, instead of showing us naked Eric and/or Jason in the final series, I'll be p!ssed!
On one hand I can't see them wasting screen time on something not important, but who really knows except the writers and actors! Maybe they are simply showing us vampire hell isn't so bad so when Bill dies it won't seem so awful? I reckon Eric has a chance of survival, but I'm not so sure about Bill. It's progressing mighty fast.
