This is just your reaction. No "we" here.
I rewatch all series last year, and posted about it.
Was only too happy to see half cooked suet pudding Perez go and shed his dreariness elsewhere.
Far sadder that Duncan got caught out yet again by bad judgement.
The point is why have the writers let both Tosh and Ruth down with no story lines and just same old scenarios.
Its really an odd decision by not just the writers but producers.
Because if as the main characters they have no substance, or progressing back stories the series will end.
