Shocking acts and major twists are par for the Sons of Anarchy course.

But in light of Abel's kidnapping, multiple sources are teasing that fans of this FX drama should prepare for a couple especially significant developments.

First, Fancast reports that Gemma will soon learn about her missing grandson. The subsequent, "desperate act" will be the character's "most shocking exploit yet," which is saying a lot for someone who committed stone-cold murder last season.

As for Jax and Tara? E! News assures readers that the riff between them won't lead to a break-up... but instead to a "huge twist" concerning the couple.

What might that be? Take your best guess now!
