Hooray! You guys are back! How we missed you.
And what the crystal is making Erin say brings to mind what Adam Jensen said in Deus Ex: Human Revolution*: "If you want to make enemies, try to change something." That line resonates with me because throughout history, you see people, nations, and empires become enemies because one group wants to change something that another would like to keep the same. Whether the cause is good or bad.
*I found out later that line came from Woodrow Wilson, but one of the trailers for DE:HR was the first place I heard it.
