Offending a luck entity - good call.

Everyone looked at everyone.
In a literary paradox, everyone avoided eye contact.
Everyone looked for a scapegoat for their actions.
Everyone looked at Jay El.

"That friggen Abatu... why do we trust him anyway?"
"Yeah!"
"Yeah!"

Jay El looked at the group, and jumped on the bandwagon.  "Yeah!" he rubbed his chest.  "Listen here Abatu, we've got some questions, and we'd like some answers."

Abatu, hearing his name, emerged.  "Hey guys.  What's up?"

In a rare moment of eloquence and initiative, Tribby started the questioning "What were you, before you were what you are now?"

Abatu attempted to arch an eyebrow at her, but failed.  He'd never been very good at that particular quizzical yet sarcastic expression, and always ended up looking more like he'd eaten something sour.  "Excuse me?"

"You heard me, what were you before you gave us this mission?"

"What mission?"

"Don't avoid the question!"

"What were YOU before YOU were born, stinky?"

"I don't know!"

"Is that seriously what you're all pissed about?  My origins?"

"No!  We have other questions!"
"Yeah!"

"Such as?"

"Well, what are we building?"

"I don't know."

"What evil are we preventing?"

"Psh, beats me."

"How old are you?"

"Compared to what?"

"Do you have any useful information?"

"If I did, I would have told you by now."

"Can you lie to us?"

"I don't see why not."

"What if I cast my truth spell?"

"Knock yourself out lady."

Med cast her truth spell.  "Okay, now... lie to us."

"(sigh) alright, I'm blooOOooOooo, sooooo very bluuuue...  hm.  It seems your spell does dick-all."

"So you could be lying to us about everything?"

"I suppose we all could be lying to each other about lying - maybe you're lying about casting a truth spell eh?"

"Stop twisting things!"

"I'm seriously not.  I'm just confused as to what you're all angry about."

"We don't know who to trust!"

"Ah."

"I mean, the Elf King could be evil and trying to raise evil, or YOU could be evil and trying to raise evil, or, or..."

"You guys didn't just wipe out another peaceful village, did you?"

"wait... you guys have done this sort of thing BEFORE!?"

(Awkward silence)

"Well, not on purpose..."
"No, not on purpose..."
"They were clearly up to no good."
"Clearly."

"I don't believe this!" Med shrieked at the group.  You're all devils!

"No, no really, we're all good!"
"Neutral-Good!"
"Well, I'm lawful neutral"
"Close enough, though!"

"AGGH!"

Abatu smiled at the group.  He decided not to mention the first time he'd contacted Jay El in his dreams, or the second time, when he'd helped Jay El save what few fairies remained alive.  Apparently, they were under the impression that he'd asked for some kind of mission to be undertaken in his name, and, quite frankly, they were kinda being dicks to him at the moment.

"Okay, bye now." Abatu finished.  "Don't come asking me for help any time soon."
