['Sons of Anarchy' - 'To Be, Act 1']

The shocking ending of last week's 'Sons of Anarchy' episode made me wonder if tonight's hour would be dominated by Clay Morrow; even in absentia, the club president casts a huge shadow.

For the most part, however, this week's gripping hour belonged to two of the people Clay has hurt most -- Tara and Jax. The scenes that featured those two characters talking to each other or to Gemma were flat-out fantastic, and once again demonstrate that the show's secret weapon isn't its crackling action but its top-flight cast. Katey Sagal was terrific this week, as always, but in 'To Be, Act 1,' Charlie Hunnam and Maggie Siff's performances gave me chills.

Many storylines are reaching the boiling point right now, but this terrific hour wisely focused tightly on the couple who have the most reason to despise everything that Clay and Gemma stand for. What made the hour tragic was the fact that Jax and Tara stand on the brink of becoming Clay and Gemma.

And they know it.
