Oh, yes, I have a few other typings too.
Dawn IEE? She was poorly developed imo.
Wesley ILE(LSI mask) basically incompetent LSI His character was intended to be killed off, if he had been killed off he would be LSI, I think the actor is ILE, he's married to Alyson Hannigan, I think some of the characters do change types in the show like Xander from ILE to IEE, I think the actor for Xander is a ethical type as well.
Buffy is a interesting show for socionics, since almost all the relationships on the show are asymmetric and/or imperfect and often within the ring of social progress, there are many benefit and supervision relationships in the show.
This makes their joining together and breaking apart seem naturalistic instead of forced but also create a certain amount of drama.
