Story Ennis had a perfectly good source of information about Jack, namely that he knew Jack's parents lived in Lightning Flat. If he'd really wanted to find him, he could have asked them to tell Jack to get in touch.
You're right about LF. That's why I inserted the 'half-heartedly' in my post. If he had been determined to find Jack, he could have done so.
The thought of story!Ennis
maybe looking for Jack never occurred to me before. And I don't know if you even could call it this. What I thought of were situations maybe on a local rodeo or stock market, where he might have gone to, talked a little business with a guy, then
potentially might have asked for a guy name a Jack Twist... These kind of things.
But Ennis, even story!Ennis, doing such kind of talk, presenting himself socially to strangers...I don't know.
Seems it is a too far streched interpretation of the sentence.
While typing Mel's reply came in, saying something similar about storyEnmnis asking people about Jack. I'll post this anyway.
