Chekov is worried.

It’s kind of weird how TOS episodes fit into nice pairs sometimes, isn’t it? Both “The Trouble with Tribbles” and “The Gamesters of Triskelion” don’t have a whole lot of plot. It only works in the episode about cute little furry creatures–and no, we’re not talking about Chekov. Also! Richard has done entirely too much research into the life of the guy who played Harry Mudd.
