Methinks this episode is 100% groovy cool beans and a good shout. Missy reaches the apex yawn point and has a gaping good gasbag about the study of yawning. Hannah is a good little house elf, as she (allegedly) gives 100% of her intention and attention to the backstory of the sock. There’s rhyming, alliteration, singing, contagious yawning, and a lot of foot chat which is, at this point, unsurprising.
