Gustav's Ploy

When Gustav saw the notification he was extremely shocked but he was quick-witted enough not to show the expression of surprise on his face.

He decided to act like his mind was actually being manipulated.

Gustav pretended to be mind-controlled by the brain tweak helmet. 

The information he gave them about the mountain phenomenon was the same as what the locals around there gave. 

He only added more details to it than they did.

He mentioned that there was an outburst of purplish electricity that sent destructive charges across the body of the mountain after the star slammed into it.

Since he happened to be closer to the mountain than others, Edan didn't have a shred of doubt in Gustav's words.

Gustav was able to easily deceive them with his actions due to the fact that they were in a hurry to get the information out of him and return him to his apartment.
