This week’s episode of All Creatures Great and Small has a more serious tone than last week’s but it fills in a critical piece of missing backstory. Siegfried has always been the kind of guy who liked animals over people, and we finally find out why. Alongside Siegfried’s past, there are also insurance scams and violent cats in the present. Let’s discuss it, but before we do, note that this episode discusses death by suicide which may be a trigger for some viewers.
