So i read that doing a lend trade would allow me to trade with this same friend but it was false and my Clamperl is now locked in his account again... would it be possible to get my pokemon back again? Also is there any way for me to safely trade evolve my Clamperl I'm really afraid of trading with a stranger since this specific pokemon is needed for story progression. Thanks again

Hello I am playing on Silver server and traded my Clampearl (ID 42672779) to a friend (Scopepo) in Kanto in order to evolve it into a Huntail so that i can progress to Sinnoh. The Clampearl is now locked in his PC and he cannot trade it back. I have attacthed a screenshot of his PC showing the locked Clampearl. Please help.
