Scenario #1
L dropped another lump of white sugar into his steaming tea, acting indifferent to the woman shouting at him. She was standing with one hand on her hip, while shaking an accusing finger at L. "Do you ever stop staring! You're such a pervert!" Misa Amane screeched. Light sat attentively on the couch across the small table, though he made no move to back up his girlfriend or defend L. The pale man excepted nothing less of the Kira suspect.
L could hear Misa fuming, but he simply stirred lump of sugar after sugar cube into his tea, practically making a sugar wet tea flavored lump. Without taking his large dark eyes off of Light, he raised an arm lightning fast to intercept the small feminine hand that was about to slap his across the cheek. His whole hand had no problem fitting over the young model's thin wrist.
Misa stood there open-mouthed for a moment, before pulling away and L let her. "Underestimating me is the first mistake people usually make." L commented monotonously, his eyes never wavering though his words were laced with suggested sarcasm.
