Although L could in no way be held accountable for the first time he didn't fully blame it on Light-kun. Slight mental instability was expected after the prolonged imprisonment the teenager had been through. Seeking comfort from a friend was to be expected. In reality the probability was at around thirty-four per cent that that's all Light had looked for in the...hug. If anything forcing the situation had left the world's greatest detective less sure about his initial conclusion.
The second incident changed L's opinion. And that time it was definitely Light's fault. The teenager had waited until everyone else including Watari had left the building and then done the unthinkable. Light-kun took the desserts tray hostage. The portion of L' brain that wasn't furious at the Kira-suspects behaviour admitted that it was a clever move. There wasn't much else to the great detective's life other than sugar and work. Sugar was the ideal target.
"You shouldn't eat so many sweets Ryuusaki. It isn't healthy." The bane of L's existence taunted.
"I need them to work Light-kun. You do still want to help find Kira?" At a glance the tone was just as monotonous as ever but Yagami picked up on the slight edge to it.
Smirking Light stayed between the tray and the detective. "Of course I do L. And because I am just as eager for an arrest as you are I'm open to negotiation."
Scowling the detective realised he'd have to agree to whatever terms Light set out. He expected Light to push for a favour like going to play tennis or taking a break. He hadn't anticipated being forced to sit on Light-kun's lap. Again.
He drew the line when Light started stroking his hair. He was not a cat and dessert tray or not he wasn't going to put up with this. Or at least the detective tried to. Light-kun had seen it coming.
"Shh. Shh. Relax, you've gone all tense Ryuuzaki. I like your hair. It's softer than I thought it would be." Leaning uncomfortably close to L's ear as he twisted a strand around his finger Light continued. "You are going to let me touch it L. At least if you don't want half of all the icing on your cakes to be replaced with toothpaste." L stopped struggling. "My toothpaste. You remember? The one you said tasted like "toxic waste"."
"You can't," L said ignoring the nagging doubt "you'd need access beforehand. And we are still chained together Light-kun."
"I'm sure Misa would do it for me if I asked her." The teenager assured nuzzling L's hair. "Checkmate Ryuuzaki." Now the world's greatest detective was trapped yet again in the lap of one of his most dangerous suspects. Only this time his hair was being molested. With a running commentary about how soft it was and how nice it smelled.
L tried to make up for lost time when Light finally let him go, but he couldn't concentrate. He could still feel the heat from Light's body against his own. He could still feel the fingers threading through his hair. And he still had the strangest feeling that he didn't mind the fact Light beat him. It was probably due to sugar deprivation. Or at least L hoped it was.
