I see two major surprises here: first, introversion. We don't hear much about time Ellen spends alone, and she seems to do very little introspection on major questions in her life. Instead, she constantly seeks company and counsel from Myrna, Dad, and MP, and indeed allows them all (and others) into reaches of her life that almost nobody thinks normal. All of her stories are organized around interactions with others--past, ongoing, or planned. She has a great deal of difficulty with individual elements of her work, such as preparing briefs, presentations, and research, but apparently shines in court and at meetings. I would have called her a strong extravert.
Second: thinking over percieveing? Ellen's mode of making sense of the world seems to me firmly rooted in sensory experiences (smell, taste, touch, emotional reactions) rather than any kind of detached analysis. If I were DUMM I might simply say that nobody of Ellen's intellectual capacity could be accused of even "moderate" habits of thinking, but I know personality typology is a bit more nuanced than that.
Speaking of which, reader's and Sunshine Girls, I'd love to know if and how I am wrong about any of the above...
On the unrelated issue of Sam, I suppose it is in keeping with his vegan and gluten-free lifestyle that he has also sworn off undergarments. However, still, for all the fooeying, I do not see any indication that he's been definitively disqualified as yet.
