I read a really good article about why Echo Zane was let behind.

The elemental power must tie into something that Zane has that Echo Zane doesn't. I can only think of two possible things: a past (read my Darth Zane theory) or his core.

Echo Zane has a windup core (which for the record I made up from pictures and put it on the wiki and you all believed it) while Zane has his Ice colored core. If the element is in the core, then we run into the problem of Pixal not having ice powers. And don't say she just didn't know about them. In The Day of the Dragon Pixal was able to clearly tell when Zane's ice powers increased, so she would be able to tell if she gained ice powers.

I really have no answers, just some thoughts.
