Back when the war first started, ponies had to break their friendships apart based on the sides they're on. This is the case with (Left to right) Windblade and Slipstream. They didn't want to break their friendship but it was must.

This is the song that inspired me to draw this;

Deftying Gravity from the Musical, "Wicked"

Elphaba, why couldn't you have stayed calm, for once!
Instead of flying off the handle!
I hope you're happy
I hope you're happy now
I hope you're happy how you've
Hurt your cause forever
I hope you think you're clever
I hope you're happy
I hope you're happy too
I hope you're proud how you would
Grovel in submission
To feed your own ambition
So though I can't imagine how
I hope you're happy
Right now
Elphie, listen to me.
Just say you're sorry!
You can still be with the Wizard
What you've worked and waited for
You can have all you ever wanted
I know
But I don't want it
No!
I can't want it anymore
Something has changed within me
Something is not the same
I'm through with playing by
The rules of someone else's game
Too late for second-guessing
Too late to go back to sleep
It's time to trust my instincts
Close my eyes
And leap
It's time to try defying gravity
I think I'll try defying gravity
And you can't pull me down
Can't I make you understand
You're having delusions of grandeur?
I'm through accepting limits
'Cause someone says they're so
Some things I cannot change
But till I try I'll never know
Too long I've been afraid of
Losing love, I guess I've lost
Well if that's love
It comes at much too high a cost
I'd sooner buy defying gravity
Kiss me goodbye, I'm defying gravity
And you can't pull me down!
Glinda, come with me.
Think of what we could do together!
Unlimited
Together we're unlimited
Together we'll be the greatest team
There's ever been, Glinda!
Dreams the way we planned 'em
If we work in tandem
There's no fight we cannot win
Just you and I, defying gravity
With you and I defying gravity
They'll never bring us down!
Well, are you coming?
I hope you're happy
Now that your choosing this
You too
I hope it brings you bliss
I really hope you get it
And you don't live to regret it
I hope you're happy in the end
I hope you're happy my friend
So if you care to find me
Look to the Western sky!
As someone told me lately
Everyone deserves the chance to fly
And if I'm flying solo
At least I'm flying free
To those who ground me
Take a message back from me!
Tell them how I am defying gravity
I'm flying high, defying gravity
And soon I'll match them in renown
And nobody in all of Oz
No wizard that there is or was
Is ever gonna bring me down!
I hope you're happy
Look at her
She's wicked
Get her!
Bring me down!
No one mourns the wicked
So we got to bring her
Ah!
Down!
