in these sentence, what does "alternative reality" refers to?

This is actually a Multiple choice from GRE. "tonic" is the answer that standard answer gives. But I am curious.
what does "alternative reality" refers to? It means that the things that might have been done or thing that have been done? As I consider, I think this blank should be filled in some word that have the same meaning of regret.
well, because I think the word "alternative" means another, and it shoudl be opposite to "what might have been"
I would be rather grateful if someone can explain.
