Theory for the New Project skins: This team beyond saving.

Sivir, as I do believe that's sivir's voice, says "No matter how far we go, we return." My theory is that they escaped just like the others but are configured in such a way they can't really do as they please. Meaning that the corporation that the others escaped from has suceeded in making pure killing machines. "We Return" Hunter, I would like to say this is the title given to the Project that follows absolute orders. This could include katarina and zed too, but I'm not sure. The demeanor I'm getting from that teaser is ruthless. Sivir, Vi, Jhin, and Vayne....no matter how far they wander off to, they are always summoned back because of how they were programmed.
