He said there's going to be a plot twist. Hmm... she was put away for 15 years for manslaughter, what kind of plot twist can there be?
Collinson told the paper: "Tracy will be back on Christmas Eve and, as you can imagine, she is the last person who everyone is expecting to see. Her family have no idea she's been let out, so they are completely shocked. But how she gets out of prison is something we want to keep a secret. I'm really excited about all the trouble she'll cause. She's always loved Steve McDonald and the fact that they have a child together means that they will always have a bond. It's going to be interesting to see how Becky copes. And then there's also the small matter of Gail. She was nearly jailed because of Tracy's false testimony, so there will be quite a bit going on between them. The Street will still be getting over the tram crash. And then Tracy's back - which will bring its own disaster for some of the characters."
