Don't give up on Scruff, I am convinced he will return, although like most the these cast these days he will be sounding different (Has Adams voice also changed?)
I'm not sure about Adam but there have been lots of changes and it's difficult to know which character is talking half the time. Well it is to me anyway but wouldn't stop listening though.
When there are two or three men talking, I find it extremely difficult to tell who is who. The only ones I'm sure about are David, Joe, Eddie, Will, Brian and Kenton.
And Rob, you must recognise him Helly. And Henry LOL. Oh and Matt was very distinctive but he's buzzed off. If he buzzes back again I hope it's still the same chap.
Rob's the one who sounds as if he's talking through gritted teeth to a delinquent who's irritating the hell out of him while struggling to contain his temper. And that's when he's talking to Helen and anyone he believes to be inferior to him which is almost everybody.
Yes it would help if they called each other by their names. Perhaps it's just us.
