as newspapers today dont tend to hire children, a modern day Tintin would run a clickbait YouTube channel, except the clickbait is 100% real every single time
he starts off as an irritating conservative pundit at 14, meets Chang then leaves the think tank paying him and launches his own independent channel and blows up shortly after. Chang helps with video editing and managing his socials and they often chat on video calls between adventures. Haddock, his foster dad, has absolutely no knowledge of his earlier videos.
I remember discussing Tintin casting choices with a friend from Germany and remarked how it was odd he often has an English accent in adaptations rather than a Belgian one, and my friend just replied "that's because Tintin gives incredibly strong English boy energy (derogatory)"
Here in the UK there's a lot of weird classism tied into accents. Today accent diversity and representation in broadcasting is actively pursued but in Tintin's time there certainly was a preferred accent to have.
imagine this exchange happens between pages 28-29 in The Crab with the Golden Claws
