Yes, EIE's even when they're brooding and simingly calm, they will let everybody know about this with their facial expressions. It's like every emotion is a little bit over the top (for the show, as a display to other people).

And I know a lot of very theatrical ESE's who are most definitely not EIE's as well.

But I really don't know exactly how IEE-Fi facial expressions look, so I'll have to check on that.
