He came upon Twilight's Lab. Twilight bolted 'crosd the room checking scanners, charts, maps, and potions.
Inferno closed the door behind him, he didn't want Pinkie to stumble upon the lab, then again Pinkie can get by anything. You think your alone and BAM! there's Pinkie.
"Hello?" he said.
Twilight jumped, she seemed to haven't noticed Inferno walk in. "Oh, Hi Inferno," she said.
Her wings were folded, thanks to the lessons from Inferno and Rainbow Dash (but mostly Inferno).
Twilight looked down and stared at a map and a scanner. "Get over here. You need to see this," she invited.
Inferno walked up to her side and stared at the map and scanner, though unlike Twilight he can't do it at the same time.
"This magic is extremely powerful, it could k'ill millions... no BILLIONS ponies."

"It's that bad?" Inferno asked.
Twilight shook her head, "It's worse, I put more depth into it and discovered that it was located in the Ruins. If the masma get's to it, it'll make everypony bl0od-thirsty and causing more deaths, this may be the biggest threat since..." her voice trailed off.
They both knew what she was going to say, "Since Blaze." Blaze is Inferno's dark-side. Inferno's a big threat to the enemy, and Blaze is the same... except the threats to his friends.
"I'll get rid of it," he said trying to add a little comfort for Twilight, "My armor will keep me alive, believe me." He bit his lip, he hoped that Twilight hasn't heard that Haephelios has gone quiet, Fate was now out of his reach and he will have to do what he believe's is right.
"Thanks," she said, "You should get started."
Inferno nodded, he knew that the sooner he got rid of the threat the better.
He started twoards the door, looked behind him. He saw Twilight going back to her routine. He softly nodded and left Twilight to her studies.

THERE'S an alternate scene, but due to some... technical difficulties I had to shorten it.
To save time I will make a summary and post the story later, THANKYOU.
