For those of you who follow Bluey, there were quite a few theories about how Brandy (Chilli's sister) ended up knocked up at the end of the episode "The Sign". I present my own theory, that the Heeler brothers all got together and made it possible several months prior. Radley's taking his turn, Stripe making use of his time to keep Chilli satisfied until they can switch off. What a couple of studs!
