Pam is currently one of my favourites and I really hope she stays.
If we were to lose Les, I think she could still work. She works well as mother figure for Billy and Honey and still has many interactions on the market.
I've said it before and I'll say it again, I think it would be good if we get to see her Mim (sister) who could possibly bring her own family for Pam to also be involved with.
On a square with Claudette,Babe and Cora, we need Pam to stay to address the balance.
