I was just mopping the floor in preparation for my house guest and it occurred to me that Lureen, (the thoughts I have at the end of a cleaning utensil!), could have been saying that line, ("Ever notice how Cowboys never dance with blahblahblah...why do you think that is?") because she was on to the flirting going on at the table which didn't involve the women. Is it possible that Jack immediately wisked LaTalk onto the dance floor to avoid further speculation that could pique the curiosity of the polite company?
Thinking back further, when Lureen asks with such a sing-songy teasing voice about why Ennis never comes to Texas and Jack always has to drive seventeen hours blahblahblah.
Fast forward now, (dizzy yet?), to the post "Deceased" phone call from Ennis when Lureen was so ice cold and seemingly rehersed in her response. She only releases when she truly understands who Ennis is. Do you think Lureen knew all along and she used that knowledge as an unspoken control mechanism.
Am I late to the party and this has been discussed before?
