She knew she was a third wheel, she knew that she would never, ever, ever understand the hells they went through, She knew that they loved each other and they completed each other and always will and always had.
She also knew she was their friend, She knew that they would never place themselves before her, she knew that they would go through any hell for her, and that they never thought of her as being "in the way", she knew that even though they didn't love her the same way they loved each other they still loved her,
She knew that even though she was the third wheel, but as Sora had told her, a tricycle won't move without it's leading wheel, and she promised to try and lead them well.
