Yes, we only see Vila alone in his room once, when he's trying to convince himself he's not ill like Jenna and Avon. They are close in an odd way, I suppose because none of them have anyone else. Hmm, I'm starting to be convinced because of how personally reticent he is, though is that an E/I trait? I thought it measured where people get their energy, and Vila does get his from being around others.

I've actually taken tests answering as Vila and he comes out ENFP for me. I'm INTP usually, occasionally INFP on some tests, and the only super-strong attribute I have is N; the others are all around 60-70%.

Greg, I meant to say before, is also INTP. Some people marry their opposite or complements--my ESFP sister married a guy I think is ISTJ--but we married likes, and it's so easy and fun knowing what the other will think about something or be interested in. The hard part is prising Greg out of the house to do things like see films.
