("Walking Dead" spoiler warning: Don't read this if you want to avoid discussion of a major plot point in season two).
After the initial shock of last Sunday's "The Walking Dead" wears off, viewers will likely be left with this thought: how can they top it before the season ends?
Don't worry, we're not going to reveal any specific spoilers — though an AMC ad inadvertently did that very thing recently. Suffice it to say that the end of "Better Angels," which airs Sunday, will come as a surprise even to those who've devoured Robert Kirkman's "Walking Dead" comics.
The entire episode is a tension-filled gem, with an unexpected admission by Lori that leads Shane off on his most dangerous plot yet, involving Rick, prisoner Randall, Lori, Daryl, Glenn and Carl. And there's still one episode left after Sunday — the second-season finale airs March 18.
