Sirius felt a sour taste in his mouth when Remus pulled away from him in that way, and his face flushed as he cursed himself for being a major idiot, and pushing him away. What was wrong with him anyway? Frustrated, he ran his hand through his dark locks, licking his lips, trying to think, and quickly. But it was too late, things were now bolluxed up. He took a step after Remus' retreating form, then another, but before he could gain on him, he was beset by some giggling girls who surrounded him and began asking him silly questions about how he was. And he realized that he had to play the part, or someone might suspect the secret he was harboring. And if that someone was Remus, why he would simply die.
He answered their questions automatically, without much thought, and his eyes never left the retreating form of his friend, his heart sinking lower with each step.
