The website alphastv.net has collected some information about Summer’s (possible) episode of Alphas called ‘Alphaville’.

As the title says, the team finds a community of alphas in this episode. They filmed it in the woods somewhere. No cell phone signals for Gary. Guest characters include Skylar Adams (Summer Glau) and her daughter, Alphaville founder Claude, an alpha called Benji who has the same ability as Rachel, Gower, another alpha who likes to play with electricity, and Bip & Tricia, Mr. Scipio’s new friends.
