I like Charlie.
As much as I hate Eastenders itself, whenever she's been on chat-shows and been herself, she's always come across as very grounded and likeable.
I'm sticking my neck out on the very first day, and predict the final three will be Brian, Colin, and Charlie.
Barring strops by one of them, or heroic acts of bravery by the others, happy for any one of those to romp it.
So far ....
