Robyq, I would suggest being extremely cautious about posting specific test results for someone else (especially an adult) without their consent. I would further suggest that questions regarding 2e should come from your friend, rather than you, and again, only with consent. (As in, please don't do either of these things.)
With regard to the general question of what testing profiles "belong" in specific fields of study or levels of education, consider that not every person's abilities are uniformly captured by the instruments available to us, for a variety of reasons. Licensed clinicians use these instruments only in context, after extensive training, and for the purposes for which they are each designed. Fields which require specialized skills are much less likely to benefit from the predictive value of general assessments.
Bottom line, in your place, I would simply appreciate that your friend has been a good sport about allowing you access to personal information, and taking unnecessary tests at your request. If they find that they have questions about themselves and their educational or other experiences, then they may wish to consider professional evaluation. But if they are satisfied with their own current growth, whole-person learning, development and relationships, then they should be allowed to enjoy them. The graduate school years are typically a lot of work, but can be intellectually exhilarating and personally enilvening. Let them be.
