I love the way Ennis looks at the card, reads it, turns it over, looks at the front, and then reads it again. Like he has to read the words to make them real, and he has to do it a couple of times for double confirmation that he'll be seeing Jack Twist again. I'm surprised he was able to give Alma an answer at all, he looked so...entranced. I bet his hands were trembling, never mind anything else!
