There is this Bounty Hunter in the Ill Repute (Bar and Brothel is the other name) who is supposed to be killed by shooting a crate of explosives behind him. I've inspected the crate with both Led and Grubb already, which is a requisite, but when I enter battle, the screen scrolls away from the crate to the right, and I can't target anything but him. I just spent 15 minutes trying anything that came to my mind. Any ideas on what am I doing wrong?

By the way, the guy literally doesn't have a health bar that could be depleted, Corgan's Observe skill revealed this.

You have to inspect the crane with Grubb and then click (use) the chain in the opening on the lower part of it. The crate is placed on the ground and when you enter the battle the Bounty Hunter stands right next to it. Boom! :D

Yes, that way. I figured it on my own actually the day after, but thanks for taking the time to answer the question!
