Meet The Characters
Eric Weiss - Best Guess: ESFP - If Will is the "nicest" of all the characters, Weiss is the friendliest; as ESFP's usually are. While not a performer in the strictest sense, he is witty and quick to liven up a boring discussion with a joke or two. He is very sensitive to the feelings (F) of others and will quickly initiate conversation (E) with you if it looks like you are having a bad day. In his last act on the series, he is seen breaking (a minor) rule in order to help his friends. He doesn't think twice about this as is usual for an SP. He has the desire to do field work, but it is just not a welcoming setting for any F-outside of SydnEy. He usually stays indoors. Strongest Letter(s): EF
All in all, and it looks like our suspicions were right as there is a heavy NT core to this cast within the main characters. There is also a strong SJ (law abiding) element. It is after all, the CIA.
