I don’t know if maybe there’s more to it, as I was just starting uni when these episodes were originally screened, so didn’t see them all - but is that the end of the ‘Les creeping through the loft’ story? It went on for weeks - is Emily saying ‘Oh well, at least I’m rid of Percy’ really the end of it?
On that subject, Percy deserved a much better exit. Couldn’t Rita and a couple of the others have at least popped outside to say goodbye? Kevin is related by marriage, for heaven’s sake.
