Original Description:
 
Soarin: You know what, Dash?
 
Rainbow: What?
 
Soarin: You really are the most beautiful mare I’ve ever met
 
Rainbow starts to blush and tries to look away.
 
Rainbow: Okay, I’ll pretend to believe that for now.
 
Dash turns her back to him, and lowers her ears as she stares at the floor.
 
Rainbow: I’m really nothing compared to other mares like my friend Rarity… I just know that…
 
Soarin has a confused expression, when suddenly his gaze becomes steady and he approaches his girlfriend and puts a hoof on her cheek making her turn back to him.
 
Soarin: You’re right Dash, you really are nothing compared to other mares.
 
His gaze then changes to an affectionate and sweet gaze.
 
Soarin: That’s because you’re already beautiful and special in your own way Rainbow Dash.
 
Dash looks into his eyes lovingly and starts to blush as he does the same.
 
Soarin: You have no idea how beautiful you’re Dashie, I know that more than anypony.
 
Dash smiles at him then puts a hoof on Soarin’s hoof who is holding her cheek and closes eyes as she caresses his hoof with her cheek with a sweet smile on her face.
