Reading this I can't help but think of a character, The Sphinx from Mystery Men, who illustrates your topic. He only *signals* wisdom:

The Shoveller: I know this guy. Big crime-fighter from down South. Big-league hitter down there. Mr. Furious: What's his power? The Blue Raja: Well, he's terribly mysterious. Mr. Furious: [dismissively] That's it? That's his power? He's mysterious? The Blue Raja: Well, TERRIBLY mysterious.

The Sphinx: Your temper is very quick, my friend. But until you learn to master your rage... Mr. Furious: ...your rage will become your master? That's what you were going to say. Right? Right? The Sphinx: Not necessarily.

(now that wasn't signaling wisdom nor maturity)
