The paladins found an old altean ship stuck in a weird hole in the sky and they went to check it out and then found shiro but shiro with a strong Norwegian accent and a braver slav and found out that this is the alternative reality and the alteans still exist but going out later that they're evil and they tried to escape but too late,they got captured.

Lance,hunk and pidge were in a cell on the ship while allura was with the other alteans who are trying to get information about a comet Voltron.
