Simmy is still stuck in 70s with Baby Yana, but every age has its Doctor and the ’74 is the year of a brand new Doctor. We have already met Bakey while he pays a visit to Rory. But when he is at home, he lives with a younger version of himself (like Simmy do)… we’re proud to introduce Bakey Jr. formerly known as the Sixth Doctor.
Try to guess what Baby Yana was trying to build ^_^
