I don't think Pam was ever trying to rip off Molly and Tyrone. I think you may have had the wrong impression Bug Girl. I bet she does do the best possible for them, especially now that the horrendous Jackie has reared her ugly head once more.
I would like to see some no dodgy dealing story lines for pam though as clearly she thinks the world of Molly and Ty.
Here's to a fast recovery Pam and sorting out everything for the good.
