Lorraine usually ends her bit with "I will see you tomorrow!" so I doubt very much whether she was referring to Spencer and Helen...would be nice though!
I really think Spencer looked happier than he has been since coming out of the house. I am sure he and Helen had a right giggle behind the scenes..ie off camera not the bits we saw whilst they were messing about as 'teasers', because they seemed very easy going with each other on screen. I think Spencer was more relaxed than I have seen him in other interviews... but then Lorraine and Helen like to have a laugh so it would have made him feel more comfortable than with say reporters or Dermot even, who just throw questions at him without really much thought.
