"If you had to ask what that creature was, then you have no idea what I seek."

She'd respond and turned to face Xion, pointing at her chest, where her heart would be. 

"I lack what you have and am looking for more people akin to myself. You aren't one of them from this exchange alone."
Emily
*She's confused. Nobody's (heh) really given her an explanation of stuff in full yet* "Explain. I'm new to all of this. I have this Keyblade thing but I still don't really understand it in full. I can barely figure out the portals thingy with it. So why not help a girl out and give me a crash course explanation?" *She asks as she summons her Keyblade for show*
Pamela
"That creature like myself is Nobody." 

She barely explained and shook her head, she saw no reason to explain the situation to someone that had no relevance to her goal but the summoning of a Keyblade changed that to an extent. 

"But you have a Keyblade? There is nothing I can inform you on that peculiar weapon, other than you should be careful who you brandish such a weapon against. It is highly coveted."
Emily
"What is a 'Nobody?' Like... Why do you presumably look different from the silvery thing? Why can you talk but it doesn't? What makes you guys different from Heartless? Also um... Why exactly is it coveted?" *She asks as she yoinks off the charm and it expands in her hand, causing the Keyblade to vanish before she slides the magic conduit into her satchel bag*
