Motan never minded telling lies, regardless of which personality he was under. Even in the 'Orderly Good' state, with an extremely upright outlook, he couldn't escape from it. After all, in the Real World, he was one person, not three, and cleaning up after himself for various reasons had become a basic operation. Naturally, this process couldn't avoid telling a few harmless white lies.
And when he was in the personalities of 'Chaotic Neutral' and 'Absolute Neutral,' needless to say, his ability to bullshit was unparalleled. He could even tell the truth in a way that totally messes with people. The latter persona didn't lack for deceiving others for various reasons, though the element of 'malice' was relatively less, such as giving various objective explanations for embarrassing or awkward situations like being late for class, forgetting to do homework, or getting lost at his own doorstep. He was certainly very skilled at that.
