Ness and Pit seemed slightly confused.

"Uh, ghosts? In that mansion?" Pit said in slight unease as he turned slightly pale. The professor nodded.

"Yep, that's where all the ghosts reside. Recently they've been going completely wonky, and I can't figure out why for the life of me!" Elvin said, throwing his hands and as such some paperwork into the air. Pit turned paler.

"Uh, I'm not a science nut, but even I draw the line somewhere!" he protested the best he could with all the blood in his body currently being in his hands. "I'm outta here!"

Wth that, Pit bolted for the door, but Ness grabbed his wrist and attempted to stop him. "Pit, wait! Don't you want to find anyone stuck in that mansion?" he asked in a surprisingly calm yet frustrated tone. Pit turned uneasy and odded weakly. Suddenly something reentered Elvin's mind.

"Wait a second! Taking a good look at you made me realize: someone who looked almost exactly like you came running up to the mansion a long while back...and never returned. Was he a hallucination?" he asked, gesturing towards Pit the whole time. Pit shook his head in disagreement.

"N-no!" he stammered uneasily as he suddenly turned the palest he could get. "T-that person was my doppelgänger!"

"Oh! By any chance did you see a blond kid go up there, too?" Ness asked worriedly, remembering about one of his friends.

"Why, yes! Shortly after Pit's doppelgänger arrived there, a young boy in a yellow and red T-shirt rushed up there without even stopping to chat!" Elvin recalled. Ness turned pale.

"Lucas!" he exclaimed in evident worry. He turned to Pit and explained that Lucas and Dark Pit could be in major trouble if they didn't help them.
