Steesh

So someone was lending me their garchomp and we agreed i would send it back once i was finished using him (shown in chat), but i didnt realise that it was a different region pokemon so i cant trade it back. Their username is 'Ravinpro1' and mine is 'Steesh'. I play on gold server. The screenshot is from Ravins perspective. Was hoping to be able to give it back asap if thats at all possible.
