[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 mane 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
