That was not a just a hike...that was an exorcism .It was such a a delight reading that scene where Lyn gets his epiphany .That his romantic feelings for Brad are no more.
To be honest I felt sorry for Brad in that last scene...he is floundering. He probably subconsciously realises that Lyn is beyond him . He tries to revert to his jocular self but it does not seem to hold . In my opinion this line is the saddest and annoying in equal measure.
“Never in my life, but like never-never, has anyone looked at me like you used to in college.”
We probably don't know what transpired during the 'event'...but that line above is an attempt of emotional manipulation..He really does not seem to notice that Lyn has evolved..to an extent that is. The saddest part in that line and that scene by large is that in that moment when Brad is his honest self, it pointless. It's a case of too little, too late.
