I don't see Rodney as a T. What about his impassioned cries to save the Amazon rainforest (the lungs of the earth)? He's also always the one to pick up on the (im)moral implications of things that Del might overlook.
Sorry to bring back an old topic.... But Delboy an ESTJ???? No way Pedro. I would of thought him as an ESTP.
Infact, I would of thought most of the cast would be some kind of SP. Cassandra, I have down as an SJ, of some sort though.
Rodney, definetly an F, I would of thought he'd be an N too. He doesn't seem to deal with concrete facts as much as Del, and is often found to be looking at the Bigger picture, or with his head in the clouds...
