The imposter had to be connected to Hannah.
Hannah and her entire family used every trick—stealing, scheming, outright taking—to strip Charles and his family of their lives.
What Hannah stole was her mother's life.
Would Hannah really stop there, satisfied?
Victoria had been Hannah's "defeated opponent," the contrast she trampled on to make herself look brighter. Victoria died, but she left behind a daughter.
When people become consumed by obsession, they keep pushing. Hannah hadn't felt the deepest thrill from crushing Victoria alone. It wasn't enough to shove one woman into the mud—she wanted that woman's child to spend her entire life being replaced too.
That's why the imposter knew everything about Selina. Why she could impersonate her so well. You don't just "pick that up." You don't just "become someone else."
Not without ten years of relentless training.
So the imposter almost certainly came from the Hill Family—likely trained by Hannah herself.
