Oblivion is a long way. It will take him a long time to get there. Heaven is closer. Naturally he will stop off there on the way but he doesn’t expect to find anything. So he will continue on his journey to oblivion.
Oblivion IS a place. It is not a void, as many would have us believe. Our hero tends to avoid voids. Admittedly it is dark and lonely and endless. Like the universe. Of which it is a part. But if you travel far enough and deep enough you will find a corner of light and inside the light you will find the lost souls of loved ones.
It is there that he hopes to find his companion. She has been gone for two years. Most people who lose a loved one get over it and move on with their lives. He can’t seem to do that. He doesn’t know why. People tell him he’s insane to pursue her. Insane to undertake a journey to oblivion.
To which he replies, For the past two years my life has not been worth living. I need to be with her. It’s worth a shot.
And he pulled the trigger.
