So... one thing that always bothered me, for the longest time... Vakama was a mask maker. Why did the Toa Metru have so much trouble learning about their masks? I suppose there is always the "I know what the powers are but how the heck do I use them?" excuse, but he could at least have told the other Toa what their masks did! And if he really did know what his power was, just not how to use it, how could he instantly use the Vahi, a mask who's exact use wasn't exactly known? Seems a bit silly that the one Toa who used to make masks couldn't figure out how to use a common mask, yet without trouble used a one-of-a-kind mask that had never been used before.
