Extroverted Sensing (Se): Greg thoroughly enjoys his time in the Unknown because he perceives it as one huge opportunity for having fun. He’s absorbed in his own playful world of candy trails and frog-naming, constantly interacting with his environment and playing with whatever he can find. He’s observant and uses whatever’s at hand to deal with a situation—sticks, drums, a jug of molasses. Danger doesn’t faze him: when about to be attacked by a savage dog, his first remark is to inform the creature that it has “beautiful eyes.” Where Wirt panics, Greg acts, calmly insisting that the most dangerous adventures are “amazing.” He prefers to take the fun option—running around outdoors rather than enter the Langtree school, though he’s eager enough to join in the students’ mealtime. He asks questions about sensory things and composes songs about what they’re doing, where they’re going, and the joys of potatoes and molasses. He tends to be rather literal.
Introverted Feeling (Fi): Greg believes that “We need to do our part to make the world a better place!” and he endeavors to act on this code whenever possible—helping the Langtree school and his “uncle” Quincy Endicott and looking after his frog. He is saddened when his efforts don’t work out and critical of himself whenever he feels he fails to live up to his standards. When Endicott gives him money, Greg throws it away because he thinks he was “pegged all wrong. I’ve got no sense at all.” Despite his cheerful demeanor, he can be hard on himself, berating himself for “goofing off like always” and allowing his brother to grow into a tree. Even when he himself is suffering the same fate, he’s more worried about having stolen a rock from a neighbor and needing to return it. Although Wirt isn’t always kind to him, he’s certain of his brother’s unspoken affection and is willing to make great sacrifices to try to save Wirt’s life.
ExtrovertedThinking (Te): Greg is considerably more decisive and action-prone than Wirt. He suggests obvious solutions to problems that Wirt complicates—why not take the tape to Sara himself if his brother is too nervous to do it? He’s level-headed in times of danger, and though he may not always have a plan, he’s always ready to do something about a problem (“spanking” an attacking dog, or stealing back the students’ instruments and holding a benefit concert for the school) and save the day. He can be pragmatic, setting aside scruples if they get in the way of getting something done, though he sometimes regrets it later (such as stealing Old Lady Daniel’s rock). Although he’s a bit nervous about having to lead when Wirt tells him he can do anything he like (“Anything? That’s a lot of power.”), he’s sure he’ll be a good leader; he’s no stranger to organizing games for him and his friends. He believes in the importance of proof, informing Enoch that they can’t be convicted without it—though his “rock facts” are of questionable truth. He quotes principles learned from his elderly neighbor, whom he considers an authority. “You can do anything if you set your mind to it,” he insists, and he refuses to give up on anything—especially not the bargain for his brother’s life…
Introverted Intuition (Ni): …and once he’s established that goal, he’s determined to make it happen at any cost. Although Greg’s not much focused on the future and tends to be quite concrete, he has his moments of intuition, such as being able to tell that something weird is going on at Lorna’s house and his belief that he can dream up a way to bring himself and Wirt home.
