Return to Ryujin Tower. When you take the elevator to the right floor, you will be chatted up by Yuko.
7.1. (Optional) Talk to Yuko
Talking to her is optional. You can tell her what you have determined or ignore her.
7.2. (Optional) Confront Ularu on the Executive Offices Floor
Imogene was collecting evidence against Ularu. Perhaps I should confront her.
Before you go to Dalton you can confront Ularu. When she finds out what you are coming with she will close the door to talk in private. Persuade her or lie that you will give her the evidence and then she will confess that she is the one behind the leaking of the plans. You will also find out that she wants to take Masako's place. You will have to choose whose side you are on.
- I'm on whatever side involves the most credits. - You will side with Ularu.
- If it means better job security, I'm on your side.
- If you really have Ryujin's best interest in mind, then I'm on your side.
- I don't care how you frame it. You're a traitor, and I'm with Masako.
- Masako's side is Ryujin's side. And that's the side I'm on.
If you take Masako's side, you will then have to decide whether to hand Ularu over to Dalton or kill her.
If you sided with Ularu and said earlier that you would hand over the evidence to her then you will be able to hand over the data disk to her or keep it for yourself and change your mind about her future fate.
If you decided to reveal the truth about Ularu to Dalton and give him the evidence:
Ularu confessed to leaking Project Dominion in a plan to overthrow Masako. She tried to recruit me, but I refused. I need to report to Dalton to give him the slate and let him know what I've learned.
If you decided to side with Ularu:
I agreed to help Ularu who admitted to leaking Project Dominion as part of her plan to overthrow Masako. I still need to report to Dalton but also make sure he believes Imogene is guilty.
If Ularu hasn't revealed to you that she is a mole:
Ularu wouldn't confess to being the mole. I need to report to Dalton and give him Imogene's evidence slate.
If Ularu revealed to you that she is a mole and you decided to kill her:
Ularu confessed to leaking Project Dominion. She was a traitor, and I killed her. I need to report to Dalton.
If you decide to kill Ularu then this decision will make the completion of the mission "Sabotage" much easier. Without Ularu, Imogene will no longer have to hide, you will be able to meet her during that mission and then she will give you a certain key.
7.3. Quest completed!
Go to Dalton and tell him what you have learned. If you decided to help Imogene, you will hand him the evidence disk. If you sided with Ularu, you will have to lie and frame Imogene.
After completing the report, this mission will end and you will receive 250 XP, credits and random items. The next mission - "The Key Ingredient" - will automatically start.
I found Imogene in the Seokguh Syndicate hideout. She had evidence to prove Ularu is the mole, but Dalton needs time to examine it.
