He’s 15, old enough to join the Russian army and check for land mines.
Take him down to the docks and sign him up for a trip back to African. Tell them he is 19 years old and wants to work his way back to the Kiwanda, or Nwanda or somesuch BS place.
If it was my kid I would give him to a traveling train of gypsies if they still existed, after beating him like a man.
