Imogen has said that she does nothing, so won't be popular with the outside world, so if she knows this why not do something about it?

As for the swearing I think you will find it dies down if Lisa leaves.
I have found myself that the frequency of my swearing increases when I was in an area with people who swear all the time. It took a mental effort to stop once I realised I was also doing it.
