Simply put, I have seen both parts of the Sons of Anarchy season four finale - and they are each terrific.

Beginning tomorrow night, Kurt Sutter will bring this pulse-pounding season to a conclusion that, I can safely say, few will see coming. Significant decisions will be made, threats levied and at least one twist takes place that changes the game entirely.

So, what can fans expect? Consider these teases:

• Someone will read Maureen Ashby's letters for the first time.
• We will see Jax Teller naked.
• Tara will attempt to out-Gemma Gemma.
• Potter will make an important point... using a bag full of sex toys.
• There will be a background reference to The Shield.
• A death will possibly plant the seeds for a major season five storyline.
• Opie will be faced with a significant decision.
