Match and Pencil have been best friends since the first episode of the first season. They seem to care more about each other and themselves, although they are nice towards their alliance members.
In the second season, both of their personalities change. They seem to care less about others and are much larger gossipers than before. They are also more jerkish like they were in the beginning of the first season. They would often insult other contestants and would show major distaste towards them. Their attitude, however, doesn't change towards their beloved alliance, although they betray Ice Cube and kick her out of the alliance in Get Digging after making an "ugly face" in front of Pencil and Match.
In IDFB, they don't interact, due to Match being in the TLC.
In BFB, they seem to be more spiteful towards others than they were in previous seasons, especially towards their alliance mates. Examples include Pencil threatening to expel Book if she doesn't help her find out who popped Bubble, using Lightning to zap others, demoting Bubble to a "bember" and a "bemb", and making Bubble cry when Pencil uses Lightning to zap Fanny.
