Return of the Zygons?

Doctor Who executive producer Caroline Skinner may have dropped a hint on one of the returning foes for Series 7.

As we've reported here, last year it was revealed that a couple of classic monsters from the 60′s and 70′s will be back.

In an interview with the producer, SFX asked if we might see the Zygons again and her answer was simple: “Wait and see.”

Skinner also teased that episode 1, written by Steven Moffat is, “going to blow everybody’s mind.”

She added that not all of Series 7′s scripts are written yet, “But we’ve got a lot of them and the ones that are written are really, really epic and very exciting.”
