No Returning Characters in Series 5
Anyone hoping for the return of old characters like Jack and Sarah Jane in Series 5 had better prepare for disappointment.
In an interview with the Guardian, Steven Moffat said that no past characters will be back this year (excluding River Song then).
“Old favourites can return, provided you can do something new and exciting with them. There are no past characters coming back in this series, but I imagine that kids would love to see Captain Jack meet the new Doctor.” Moffat said in an interview with the Guardian.
There’s obviously a chance Moffat could be hiding the truth to make for a surprise return, but at the moment it looks as though we’ll have to wait for the next series for any reunions.
