This princes matter is becoming even more intricate, now even with spirit guardians; I wonder how many princes will be on the ship.
Since nen can influence other persons in terms of attack/targets, I don't see why it can't be transferred as well. And being unable to be controlled, it would still result inferior, in some ways, to a personal nen power, so I don't dislike that much this idea.
I liked Kurapika explanation about the emotions while revealing powers, watertight. Personally I would have chased down the Monkey already, but having empty hands and with Beyond more dangerous maybe it's better to wait wrong moves. With this, this matter will pause and might favour the princes arc instead.
The raising offers might involve Silva and Zeno, who always seek a good pay.
