[Twilight Sparkle] 
When I was just a filly I found it rather silly 
To see how many other ponies I could meet 
I had my books to read, didn't know that I would ever need 
Other ponies to make my [bad word] 
But there was one colt that I cared for 
I knew he would be there for me 
My big brother, best friend forever 
Like two peas in a pod, we did everything together 
He taught me how to fly a kite 
(Best friend forever) 
We never had a single fight 
(We did everything together) 
We shared our hopes, we shared our dreams 
I miss him more than I realized, it seems 
[Rest of main six] 
Your big brother, best friend forever 
Like two peas in a pod, you did everything together 
[Twilight Sparkle] 
And though he's oh so far away 
I hoped that he would stay 
My big brother best friend 
Forever 
Forever
