Former Doctor Who star Billie Piper has been chatting about her return to the hit TV show as Rose Tyler.
Billie played the Time Lord's assistant for two full series, before deciding to quit in 2006. But now she's back.
Rose is one of a few characters from the Doctor's past who'll be appearing at the end of the current series.
"It means so much to me, this show, and so do the people that make it, so I really wanted to be here for these final episodes," she said.
"I wouldn't have missed this for anything."
Rose will be back on our screens in an episode due to be shown on 21 June.
It will be her first full appearance since the Doctor left her on a parallel-world beach at the end of the second series.
Billie said she'd had to watch a lot of the old shows so she could remember certain things about Rose, but also promised a few changes for her character.
"She has changed," she told Doctor Who magazine. "She's hardened. She's been through a lot in her parallel-world. I think she's been through emotional turmoil.
"She's quite sad and lonely, but also really bolshy and - that great quality that Rose has - just so headstrong and single-minded."
