I think they complete each other, yin/yang, not that Jack only completes Ennis.....what i see is Jack bounding ahead like a puppy, eternal optimism, always dreamin'...regardless of the consequences unfortunately...we all love him for this but it's his character flaw....and ennis completes him by bringing the other side...you have family responsibilities Ennis reminds him, etc....and vis versa for ennis' character flaw
I definitely think this thought is right. Do y'all know anything about the Riso-Hudson Enneagram Personality Type system? Jack is definitely an Enneagram 7 "the Enthusiast" They're always interested in the next fun experience they can have and are really hyper and involved in life with a very positive outlook. I'm very much like that as a person. They run toward stressful situations with enthusiasm and avoid bad feelings by substitutin another expeience for one that just hurt'em. They run to some type of substituting activity. Hence, Jack goes ta Mexico.
Personally. when I get turned down for companionship for a date, or just by a friend ta go somewhere, I say: "Damnit, I'm not gonna just sit there at home an mope, I'm goin anyway and enjoy that experience just ta spite whomever. Fuck'em!" And actually I've had some of tha best times in my life doin just that. I think he's mad at Ennis and upset and his trips ta Wyoming and Ennis are his excape from life as well as his love. That's been taken way and he's not expected home for a week an he's mad, so why tha hell not, Damnit, I'm takin my vacation, escape time in my own way. Course, he's tryin hard not ta think of Ennis and his own pain and probably is envisionin himself with Ennis tha whole time he's whorin and drinlin in Mexico.
Also, while on this topic, one aspect typical of many Enneagram 7's is that many view sex as friendship, advantageous activity or recreational activity seperate from love. Their concept of love enters into their perception when an emotional connection happens usually due ta non-sexual events of deeply self revealing converation that gets them underneath their more supeficial "Pie-in'tha-sky" attitude. Where bluebirds sing and there's a whisky spring, right? Their real emotions are deep down, covered by hyperactivity and attempts ta keep themselves busy at any cost. Many 7's actually fear relationships because it might limit tha range of things they can do in thier lives and they'll slow down and get depressed. But if a 7 leans 6 towards Loyalist, if someone breaks though that shell (one Ennis Del Mar, a deep thinkin, depressive Enneagram 4, the Individualist - Jack's exact opposite), then a really, REALLY strong bond can form btwn the both types. That's why reall shy, quiet people like sometimes like ta hang around reall silly, hyper folks ta live through them vicariously
Here's a link to the Enneagram website, take tha test and see what you are. Also, most bookstores have Enneagram books that explain tha system in depth. Lemme know what y'all think
