Extroverted Sensing (Se): Caleb relishes adventure – so much so that at nineteen he left home to join a whaleboat crew. He is aware of his environment and quickly able to adapt to it, which increases his odds of survival considerably, but his tendency to leap on an opportunity (ranging from stealing the coat off a corpse and pretending to be someone he isn’t to sneaking behind enemy lines to rescue a friend) often places him at great risk. He doesn’t seem to mind; little intimidates him.
Introverted Thinking (Ti): He thinks fast and on his feet, noticing logical chances to act and seizing upon them without hesitation. He is somewhat detached, with a sharp tongue and a quick wit. His problem solving skills get him into hot water and back out again. He is rational enough to advise caution at times, where it is needed (he told Ben not to rush into battle, his sound advice was ignored, and it backfired, resulting in his father’s death).
Extroverted Feeling (Fe): He is charming but also has an explosive temper. His outrage at the death of his father has manifested in public swearing of revenge, and a desire to see “justice done.” He deeply resents Ben’s mistake and does not bother concealing that fact. On the other hand, he is good at comforting his friends, offering them moral support, and urging them to join him in “the cause.”
Introverted Intuition (Ni): His desire for “greatness” influences many of his decisions. Caleb is not always great at foreseeing the consequences of his actions, though he does devote himself wholeheartedly to a single pursuit once it is in his sights. His “bad feeling” about rushing into a battle wound up to be a gut hunch that was right on target.
Note: It’s been nine months since I saw this series, so I’m typing off memories. There’s a small possibility he’s an ISTP.
