I think the programme got such flak for the whinny accent they gave Vicky, they've decided to tone it down a bit - if they needed it back she could do it, but shes probably glad to let it go.
There was one brief comment scripted about it along the lines of Dennis asking where Vicky's posh new accent had come from and the excuse was she'd picked it up travelling around Europe. As you do I suppose. lol.
