"damn." lavi thought, " and i was just starting to put things into action, panda-jii's gonna kill me if he finds out about this. unless"
lavi turned to face allen, who was about to go and tell bookman that he found lavi, and then report to the supervisor's office for his next mission.
he put his hand on allen's shoulder, stopping him abruptly.
"huh? lavi, what's wro--" he was cut short by the most horrifying sight that he had ever seen in his entire life. maybe even scarier than an akuma's soul!
(but not master cross' debts, that's for sure. :) the older exorcist was looming over him, like a lion that has just caught a mouse and was thinking of playing with it before it's untimely end.
allen thought he was going to die.

"hey allen..." the lio-... ummm, lavi, began. "don't you wanna know...'the secrets of the world?"

'the secrets of the world', lavi thought, would make a great stall tactic to halt allen from telling bookman where his predeccesor was.
allen, obviously scared to death, could not think properly in this, or any other situation, just screamed, "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHH"
now, it would have been heard over a long distance if lavi hadn't kept his hand over allen's mouth, to muffle the screaming.
"oi! oi! oi! what's wrong!! i'm not THAT scary! quiet down! he might hear us!" lavi hissed.
"mm-m-mmmm--mmmm-mm-m!?" allen replied.
"huh? oh, sorry. what was that again?" lavi removed his hand.
allen gasped for air, until saying, "i said,' yes, you ARE that scary, and who might hear us? bookman?" he finished, leaning on the gaurd rail that prevented people from falling to the depths below.
"uh.. no, nevermind that..." lavi paused, looking over his shoulder to see if anybody was listening in. "anyway," he continued, " don't you wanna know THAT"
"that...?" allen repeated. then he thought about it. what harm would it do to know the secrets of the world? he thought.

a lot of damage, apparently.
