You're an alien. You're a Grey, which also happens to be your name. You crash landed on Earth and unfortunately all of your fellow Greys are dead. But, "luckily" a friendly South American tribe that lives along the Amazon river has found you and is willing to help out! You think, you can't actually understand them. They've brought you before their tribal chieftain and shaman. The Shaman being a man of the world wears a Baseball cap from a time some UN delegation visited him and dropped off a bunch of stupid tat while doing an exploitative photo shoot for a charity drive none of them ever saw a dollar from. You of course don't know this, nor give a shit. Not going to mince any words about your situation. You're well and truly fucked. Think fast and be smart, Otherwise, it's game over. You decide to...

>Say hi

>Scream threateningly at them

>Vaporize somebody with your glowing stick o' pain

>Make a universal gesture of peace and love. You stick your finger into the air and pretentiously draw a circle in the air. Much wow, very deep.

>Flip one of them off with the universal sign of displeasure. This is a much less flattering gesture. Combining this with vaporization might be a good combo, I dunno.

>Do something else. Your ship and all other gear from it is gone, so it's pretty much you and your primary stick o' death and pain. Don't worry, only you can use it and it never runs out of pain juice. However, you can also apply it for non homicidal or sociopath actions. Like for example, performing clean (but simple) surgery. Sort of cutting wood (burning through it). And, making fires.
