Swindler power

By Erny, in Cosmic Encounter

Congratulations! I have important questions that I cannot understand how to say.
1. "You and your mark then exchange everything in the game, including physical seats, alien powers, player colors, ships, hands, systems, planets, colonies, etc." OK. As for us two or ALL players in the game?
2. "the power to Panic" Can it be lost due to the small number of home colonies? If so, whose "Swindler" or "mark"?
