For those of you who have seen the movie, what type do you think main characters WALL-E and EVE are?

Personally, I think WALL-E is SEI, but could also be IEI. EVE, I'm not really sure. I think it could be beautiful ILE-SEI robot dualization, but I might be biased.

WALL-E seems to have a definite Si caregiver role in the movie. EVE, not sure; her character is a little harder to pin down. She's a little more aloof. Definitely a logical type, though. Maybe Beta ST? Definitely out to lunch with Fi, in anycase, lol.
