that I think you will find illuminating

I admit I wouldn't have thought of the Evan-is-the-descendent theory myself, but it makes perfect sense.

I think Ruth is a red herring of sorts, and Tom will kill her (maybe by accident in the end) and right before she dies, she'll say she had a secret kid, who either ends up being Evan's mom or Evan's grandmother, depending on timing.

She will have sent the brooch away with the baby, and the brooch will be in Tom's basement where he keeps his dead wife's things.

Once he learns this and Ruth dies right after confessing, Evan will start to become possessed with the island like the previous guy was.

It totally fits because it gives Tom an impossible problem to solve for the next season(s), and Evan is already kind of a troublemaker, galivanting around the island at all hours of the night.
