Any way you look at it, how ever Emcee survives the war -- if he emigrates before/during the war or if he makes it out of the camps alive -- he's going to be burdened with so much sadness. Finding Milliways again would probably be painful, but he'd be grateful for it anyway. He still smiles and laughs through the pain but anyone who knew him would notice that he's not the same and never will be.
