In Friday's episode it says that "Dot spots a familiar face and finds herself reminiscing". I then thought this was going to be the returning Colin Russell but cast lists show he's not back till next week. So who do we think she's going to spot Friday then? Grant? Max? Cora? Charlie?

Ashley Cotton back from the dead!?

Colin - his name won't be cast list so people who don't know he is returning won't be spoiled

The BBC article states he is only back for two episodes, which are Thursday and Friday next week. If he appears this week it will be three episodes.

So either the article is wrong or Dot chats to someone else. Grant perhaps?

I think its Colin
