(( OOC: I couldn’t stop thinking about “Uncle Kingsley” after this ask I got and so… here you go. ))
Teddy Lupin didn’t know Kingsley Shacklebolt as anything other than the Minister of Magic until he was eleven years old.
On a school visit to the Ministry, as was the tradition for all first year Hogwarts students, Teddy was caught by a ministry official as he attempted to sneak past one of the guards for a dare, wearing the face of another employee. The resemblance was uncanny, however, a pint-sized eleven year old in Hogwarts robes sporting a handlebar moustache was likely to draw suspicion.
So when the Minister of Magic himself swept past with an entourage of at least six other wizards, calling in their direction: “It’s alright Babbage, young Mr Lupin is with me” and thus causing the jaws of twenty first years to drop, Teddy himself couldn’t have told you what possessed him to shout out across the foyer, “Cheers, Kingsley!”
And when the Minister’s eyes crinkled in silent laughter and his hand gestured for Teddy to follow him, Teddy did so, leaving behind his stunned teacher spluttering in astonishment.
