Yes! Especially in the quote "Ennis, quit hammering and get in here!" -- Jack says Ennis's name in such a wonderfully sexy way. And the way we see him smile at the end of that scene (right before the actual FNIT scene) -- it is as if he is telling himself: I have him now! -- where I want him!
He was cute and sexy there indeed!

I mean - Jack in the tent! Not even Ennis could resist.

Anyway, I was reffering to all of Jack's way with Ennis - he pronounces his name in so dear way. It is more that obvious what Jack feels.

When he said: What in the hell happened (Ennis)? (after mule was scared by a bear) This question could have absoultely been raised without pronouncing the name, but in that one word - "Ennis" was compressed all his love for his friend. Saying Ennis' name was very significante IMO. And cute.... and sexy...

And except before reunion kiss, I can't remember even one time when Ennis let himself pronounce Jack's name. That is also significante!
