Prediction: Aplha (the rogue) realized Echo was like him in that she eventually would retain her memories. He is now training her with 'powers' and seeing if she is really worthy...like he's sending her out on missions HE designs so he'll get certain traits, this one was the crazy outdoor skills. At the end of the season (or close to it) Echo will finally start to remember all this and he will try to get her to go rogue to fight against the dollhouse. So, in short, he's training her to be Peter Petrelli.
