I think GG based the Chuck and Blair and Nate triangle in season 1&2 on Scarlett, Rhett, and Ashley, though Serena is no Melanie haha(I still don't know why Blair is friends with her, she is like the worst friend ever, the kind of friend who wears a white Valentino dress to your wedding and flirts with your groom)
Agreed! Seriously, I feel like Serena becomes worse at being a best friend with each season that happens. Her character in general is just too much for me though.
