I think the concept of fictional characters breaking the fourth wall to find out about their own ships is always funny, but I need you to imagine lawlight learning about lawlight for a second. Light's face goes completely blank save for a violent eye twitch while he internally cycles through all five stages of grief and at least 10 emotions not yet recognised by the field of psychology within a matter of seconds, after which he plasters on a very strained polite smile and asks what "law" stands for in the most fake saccharine voice you've ever heard. L tries to murder Light with his bare hands. Light decks L in the face while getting choked out and weasels away, politely excusing himself for a minute, then L drops dead immediately after. Love loses, roll credits
