Stone faced stoic would be a good word combo to describe Rex. Because really, most look it in the eyes and are hit with a "wow, what an unmovable guy.". But this is not entirely true. He smiles(a small quirk of the lips) when seeing cute animals. His brows furrow(accompanied by a slight pout) at a particulary bothersome puzzle. Relief washes over its face(shoulders slouching over) when the work day is over. And a soft look of serenity(cheeks softly blushed) graces his face when around those it loves. So yes, Rex does have a very stoic face, this is true for most of the time. But never a stoic heart.
