Vote Soren I hope this isn't biased but I believe my logic is sound (pun intended) reading rainbow "they will feel an urge to complete the command for the next two minutes. If the victim reads another note in that two minutes, the timer is reset, and the strength of the new post it note is improved." (unless all the notes are stacked in the same room the effects won't stack to 3) Marco Polaris's greed for time causes his nen to defeat itself because I'm hiding for 3 minutes (it breaks the two minute stack time that is required from post to post inorder to boost their power.) there is no chance for the hatsu notes to stack and if they don't stack up to 3 there is no way Soren would be willing to do something so countering to his mindset as randomly activating ren when he's on a stealth operation. I think the notes will successfully burn Soren's time preventing him from going for his secondary objective but not burn his cover because there will be at least 3 minute gaps of time between the second note and the 3rd note. which means the stack would reset before he read the ren command and would be able to disregard it since being caught is basically against everything he stands for as a hunter. he'd have to fall back and retreat to his team with the information he's gathered.

Emeralda should be capable of completing her mission with time to spare and should move on to the secondary objective.
