Well, it's not what he's doing IC, it's his OOC comments. Manny wants the game to be immersive, so he's making the players suffer when the characters do, and Rube is helping his brother. (It's a wonder Manny didn't throw a glass of ice water on Lex each time Sokko fell in the water while talking to the princess.) Nice people normally don't say things
like this. That's pretty evil! And funny. As with the romance scenes in Darths and Droids, the distinction between what's IC and OOC is becoming very blurred at times. While OOC, Rube is acting evil, like Azula, at least during the current pages.
I'm loving all of the "That's not how roleplaying works!"
