This is a wonderful story that really shows how much Fraser loves and cares for both Rays - not just the Ray for whom he has romantic feelings. I like to believe that Fraser's heart is big enough to still love Ray Vecchio very much even if Ray Kowalski is his romantic partner, and I like the very realistic way that Fraser and Ray Kowalski admitted their feelings to each other. Based on what I've seen in the series, I can't agree that Fraser and RayK were a romantic couple during the series; they just don't seem like close friends. But anything could happen after "COTW."
It's also great to see RayV NOT paired with Stella (sorry, but I can't stand her and think she would make all of our guys unhappy!), and for Fraser to be happy to return to Chicago, because he knows that RayV needs him and wants to still have a close relationship with him. I like to think that Chicago becomes "home" to Fraser because he has an adopted family there - the Vecchios.
