Who would be most likely to make up a code language with his/her friends?
I think Finn, Julian, or Asher would but for different reasons.
Finn would if he and someone else like his sister Lacey were kidnapped like by zombies or something (pirates is more realistic) so they can communicate without anyone else knowing what they were saying.
Julian would do that too, but I think he and Asher would also do it for fun and because it’s cool.
