Wait! Either I completely missed something or there is something missing from the end.
In the beginning it says something about Ryan needing some sort of red pills to survive. But in the later chapters there were only a couple mentions and then they dispeared... I think.
You may have explained it in one of the chapters and I am having serious memory blank but if not I think you should explain what happened with the pills.
Other than that I really liked this story. It was a happy one :) I found it very amusing picturing the four of them grabbing the vodka bottle from each other.
