"Varian... might be alive." Sarah bit her lip and said.

"What?!" Seth's body stiffened and he couldn't respond for a moment.

"W-what do you mean? Didn't he die in the blast?" He stuttered.

"That white light ended just before me." Sarah recalled the scene she'd never forget.

"But the reports said it engulfed him." Seth countered. He only wanted to know about Varian now.

"It was dangerous, but what he had to face was the edge of the blast, not the center." She looked at Seth and saw him looking at her with disappointment..

"This is due to self-destruction of CTF." Seth's hopes vanished and he sighed.

Indeed, staying at the edge of normal blasts meant receiving least damage.

But after research on site, it was concluded that these blasts maintained a high intensity even before the end.

CTF blasts weren't normal explosions. They worked on a space range. It was like the energy was confined to a particular space.
