Of course,we have said several times before how they get to express their feelings by means of the body language.And that very often this speaks more clearly than any word they could pronounce;and a great part of this expression comes from the superb Jake/Jack's eyes and the way he "speaks" with them during all the story.
Certainly

His smile is many things including the fiery one, but I did always think this comes from his eyes too. Even though they're blue like droplets of water falling from a clear blue sky.
I remember how peculiar his glance was just before "more word you spoke in the last two weeks" He smiled with his eyes and caught me (and maybe Ennis too

) on fire. Was something hazardous how this spread to Ennis, cracking that heated, sexy grin from the side of his mouth, "..that's more word I spoke in a year" The rebound expression from Jack then seemed to carry something surreptitious to the face of contemplation, an index to a trigger. To me it was like Jack had toyed long enough with the chemistry, drunk as he might have been, and reached a point of no return as far as his character went. He was ready to
blow and in some fashion did.
