After reading the notes from the Thieves Guild, the group decides to visit Pietro Petrelli's Poisonous Pets to inquire about Tress' visits. We learn from Pietro that Tress has put quite a large deposit to be next in line to purchase the next green drake that will be available for sale. Pietro is also inquiring about the egg that got lost in the shuffle during the auction and would be willing to pay quite a price for any information, the egg itself, or its content. From the conversation, it sounds like Pietro knows more about the contents of the egg that he is willing to share. For example, that the creature coming out of the egg would like metals.
