"Well yes... You see me and Dr. Finklestein were trying to figure out *What* These creatures were first... Then worked out what they were after... Sunset over there arrived near the tail end of our musings."

Jack would say and cross his arms as he explained. 

"They were after the soul... Or rather we switched to calling it a 'heart' since that's what it looked like after a person met their demise from one."
Marcus
"Yes... Yes. But I have created an *Artifical* Heart! One that these Ghouls cannot resist its allure and thus bend to our will!" 

The mad doctor would say with something of a nefarious laugh.
Lillian
Meanwhile, 3 kids would nonchalantly walk by everyone else, giggling to themselves as they seemed to be friendly with one another.
Tammy
"An Artificial Heart you say? Now that's something I have to see."

*Ikazuchi noticed the kids and raised an eyebrow, but decided to pay them no mind. Instead, turning his attention to Sunset, since Jack mentioned her.*

"Was this *Before* Or *After* Your big darkness freakout in 'you-know-where,' Sunset?"

*Ika said, in reference to what happened back in Traverse Town after the fight with Elsa.*
Latanya
"I... Believe it was before i met that Elsa lady... Like i felt it here first thing..." Sunset sighed and rubbed the back of her own head.
Joseph
"Greaaaaat... This isn't helping our case with freeing Sunset from Darkdream... And what if this Artificial Heart gets tampered or starts to falter? That would make this a bad time..." Rainbow crossed her arms.
Edward
"I doubt that would happen, otherwise we'd have to defend every citizen alive to the fullest." Rarity also raised an eyebrow towards the three kids but unlike Ika she kept a close eye on them every time she shifted her vision to the kids and the group of heroes.
Jerry
*Xion just watches the kids closely while trying to listen to the conversation but having issues trying to figure out what the hell they're talking about*
