Speaking to SFX in the magazine’s new issue, Gillan commented: “I think [Amy]’s going to develop a lot. Amy’s very guarded, and doesn’t like to show her emotions, because she doesn’t want to show her vulnerability.”

She continued: “She has trust issues with what happened with the Doctor when she met him as a little girl. And she’s kept that hidden in the last series… And I think we’re going to see that guard start to crack.”

Series 6 of Doctor Who begins on Saturday 23rd April on BBC One.

Issue 208 of SFX magazine is available in shops today.
