over a year ago:
First off; You have to keep in mind that House is going to say ANYTHING he thinks will keep Brennen from quitting. By Brennen quitting, it throws the betting (chase's game) off. So House's first response is probably more personal. House is miserable and in pain, so he figures EVERYONE has some sort of misery and pain...Lets all try to keep it at a minimum.( Ever see Star Trek V...Kirk "I need my pain")
#2. Again House just wants him to stay, at least until all the betting is over. And its true. if Brennen leaves and goes to the congo, he'll go without his fiance...and be miserable. If he stay's for his girl, he has to practice medicine and be bored...misery!
Hope this helps...
