Russell T Davies Discusses the Role of Katy Manning in Sarah Jane Adventures

In the latest issue of Doctor Who Magazine the former showrunner insists that when Jo Grant shows up in Death of the Doctor, she's not just there to show her face.

"There's no fleeting cameo stuff, it's all full-blooded, with lots to say about Jo's life since we last saw her. I'm glad it's a big, proper meeting. . . . I love that moment in The Avengers when Tara King and Emma Peel pass on the stars, but a couple of lines wouldn't be enough for Jo and Sarah Jane. I wanted more!"

Davies interview with Doctor Who Magazine follows a previous interview about his SJA story with SFX. SJA Producer Brian Minchin, however, mentions something a little more disturbing.

"[Jo Grant] doesn't just turn up and talk about the old days. She's there with her grandson Santiago and they're thrown into the middle of a proper adventure."
