We dont even know if he's still alive or satoshi is a single person or a group of people.So no one really knows about showing up because this is something that remains to be mysterious after all these years.
Satoshi is a single person and once he launched the whitepaper and after launching the first version of
BTCitcoin many OG helped him in improving the software. The idea that he was a group is just bull shit, Satoshi did register the initial websites including the first SMF forum in the old domain and once he left, he handed over everything to Gavin Andresen and other users here. If it was a group they would have continued everything rather than giving everything to the users who were active here.
