The actress - who plays a girl that is able to heal herself in the series - said that she has been concerned ever since the show began that a supporter who takes the programme too literally might one day go too far.
"I'm just afraid somebody's going to stab me one day and think that my power is real and they expect me to start healing. I've been thinking about that since the first season," she confessed to Showbiz Spy.
"I'm like, 'What if somebody really thought I was indestructible?' Because I've heard some wacky things come out of people's mouths that you go, 'Guys, it's not real'."
