Hi forgive me if this is a stupid question but I don't want to go through the pain of rewatching the season (one time is quite enough). There where some vids last summer of the filming of season 4. There was a scene where it looked like Mrs Hudson threw some keys to John from the window. There was also a scene that included a firefighter engine and people running from an assumed explosion at 221B. I don't think those scenes ever made it into the episodes did they?
