Riku was lost in his emotions and didn't even notice his best friend approach him. It wasn't until the boy's words shook him out of his tunneled state that he even realized he was still outside of Merlin's House. he looked up at Sora, trying not to glare but wanting so badly to just punch through a wall at the moment. He didn't want to get Sora upset, but upon his most recent decision, that would be inevitable.
"It's nothing," the teen murmured, getting up and onto his feet.
He figured things would go smoother if he didn't tell Sora what he was planning to do or where he was going. So in an attempt to keep the peace Riku began to walk off towards the stairs leading out of the Bailey.
