When you regain control, you find yourself in the northern-west part of the Market District in the northern Seattle. Your new task is to find Hank, who has betrayed you during exploration of the prison. Start attacking nearby DUP soldiers but remember to regenerate power, which is probably low after encounter with Augustine. You don't have to destroy nearby armor carriers, as they shouldn't be active. But beware of snipers. Find and eliminate them before they shot you down.
After eliminating DUP soldiers, get on the roof of high building and press Up. It lets Delsin determine the way he should follow to find Hank. Your new target is a big crossroad in the Georgetown, on east from the beginning location. When you get there, be ready to eliminate a big group of enemies, among which you find also an elite scientist and heavy armored ones. So you should use the strongest powers and, in case of need, retreat onto the roofs.
Make sure you eliminate all enemies and head for some higher shelve. Press the Up and find Hank. Now you need to get onto the skyscraper's roof in the southern-west part of Belltown. When you get on the roof, begin with killing snipers. Prepare also to shot down a new helicopter. As in the previous cases, use the most powerful attacks and avoid its rockets.
Remain on the roof where the last encounter took place and use the phone for the last time to radar Hank. You have to reach the marine in the northern-east part of Belltown. Here you find Hank.
After you approach Hank (it is a good idea to fly there) and land any attack, against him (even the weakest one) you will watch a cutscene, featuring him, and you will have to take another important decision(the above screenshot). If you want to gain good karma, you need to let Hank escape with his daughter (the blue option - Spare Hank). If you want to gain bad karma, you need to murder Hank, as a revenge for the death of Reggie (the red option- Kill Hank). Regardless of your decision, this mission ends here and you will have unlocked access to the Ascension mission.
