When L had that cute lil smiley moment when he’s first meeting the task force and is all “The good guys always win” what do u think that was about? Do u think he really believes that or was it him trying to motivate the guys or L just being weird as usual? Or maybe just the writers wanted to make him have a cute little moment? It never seemed congruent with his character to me? The strawberry Mogi scene too tbh. Idk maybe his personality/humor is more silly than I initially headcanoned.
That scene is a bit hard to interpret to me as well! I remember it being commented upon in the HTR13 book too:
If I had to try to pin it down, I think that maybe L is just being slightly cheeky there? He might not 100% sincerely label himself something like "the good guy," as he straight-up says at times that he doesn't think he's that morally superior of a person, and that he's mainly just a detective for the fun of solving the cases - but he's also pretty cocky and confident that they'll be able to win, so he's capping off his speech with a saying that he thinks will jazz them up a little bit. Something along those lines.
