What's happened to Amy, the character played by Mira Sorvino on The Intruders? She seems to be hatching some big plans, judging from this exclusive clip from Saturday's episode. No wonder James Frain looks terrified.

Spoilers ahead...

In last week's episode of Intruders, there was a surprising revelation: Amy Whelan, the wife of John Simm's character Jack Whelan, is actually the mysterious Rose, ruthless leader of the immortal body-jumping Qui Reverti. And it looks like Amy doesn't live here any more.

Here's the official synopsis for Saturday's episode of The Intruders, airing on BBC America at 10 PM after Doctor Who:

Rose confronts Jack about the cause of Amy's recent strange behavior. Meanwhile, Richard discovers a secret that could destroy Rose's ascent into the Nine.
