Instead of talking about anything that isn't completely obvious, like "WHY DID PEOPLE DO THAT?" the party asks Emeraude if Lambda is human, because no one heard or saw fucking anything.

She tells us definitively that Lambda is not human: it is a monster that infects and feeds off other lifeforms. The party realizes that Richard may be infected by Lambda, and therefore we'll have to fight him.

Sophie is still experiencing feelings. "I must destroy Lambda. But Lambda is..." She asks Asbel to tell her what Lambda is, and Emeraude cuts in to be all "KILL IT KILL IT KILL IT."
