The EMT isn't producing any real Glamour right now as he is simply doing his job in a professionally detached manner. You can attempt to harvest from the Banker, but doing so will require you play off of his fear, which is directed directly at you. It'll be an intimidation roll based on Presence or Manipulation depending on how you go about it, and will enjoy a +3 bonus from his rather intense emotional outburst of fear already directed at Perry. However, from Perry's current demeanor I'm assuming he will not be pursuing this course.
Additionally, I will wait to post the results on your use of Growth of the Ivy until after Shin and Green have responded, but his current drive is a fear, not a desire, so will not be changed by the contract.
