Mass Effect 2: Thane: Sins of the Father - walkthrough Mass Effect 2 guide, walkthrough

Last update: 02 June 2021

Description: This quest should appear in your journal after completing several missions following your trip to the Horizon and naturally you must pay Thane a visit to learn more about his problem. Thane can be found in a life support room on the third deck of the Normandy and during the conversation you should agree to provide help in locating his son Kolyat. This mission can be continued by opening the galaxy map and plotting a course for the Serpent Nebula. Confirm that you want to dock on the Citadel.

Wait until you're transported to [Citadel - Zakera ward] and go talk to Captain Bailey (he can be found near the starting area - in the C-Sec HQ). Mention Thane's son during the conversation and Bailey will direct you to talk to a guy named Mouse. This person can be found in the eastern section of the Citadel. It's the 28th level of the Zakera ward, near Rodam Expeditions store (second screenshot).

There are three ways of obtaining the information you need from Mouse - you can choose renegade's interrupt (first screenshot) and force him to give you the answer, you can choose a special dialogue option of an idealist or a renegade and you can also give him a bribe (3000 credits). Notice that you can decide what to do with Shepard's WI he's selling - you can demand a copy, force him to stop selling the software or demand a share of the profit.

After you've talked to Thane you should save your game and then you'll have to return to Captain Bailey to inform him about what you've discovered. Continue talking about Thane's son and demand that you wish to interrogate Elias. You can now choose Thane to become a good cop (if you're a renegade), a bad cop (if you're an idealist) or you can improvise.

The easiest way to obtain the information you need from Elias is to keep choosing renegade interrupts (first screenshot). If you're playing as an idealist it's going to be tougher and you should consider switching sides often (between being aggressive and understanding). Thankfully even if you fail and his lawyer shows up you won't risk failing the mission. All you have to do is to inform him that you only wish to know the identity of the person that's supposed to be assassinated and you'll be allowed to continue this quest.

Talk to Captain Bailey for the last time and you're going to be automatically transported to a new area - [Citadel - Catwalks]. Start off by going to your right and examine a datapad (first screenshot) to acquire a new plan for a research project. SAVE your game, position Shepard above the target (second screenshot) and press the action key to start following Joram Talid.

The objective of this part of the mission will be to follow Joram using the balconies. It shouldn't be too difficult, however you will have to report each time he's made a stop. Start off by heading to your left and going through two sets of doors. Wait for Joram to approach his first stop (first screenshot), target him and press the action key to report to Thane. Notice that you don't have much time to send the report, so you can't waste time wandering the area.

You may now head on to your left, going through two other sets of doors. Once again you must wait for Joram to show up and to send an updated message to Thane by pressing the action key. Go to your left. In this case you'll have to wait for Joram's bodyguard to enter one of the stores before "scanning" him (second screenshot).

Get ready, because as soon as the bodyguard has left the store your target will start running. Keep making left turns (first screenshot) and you should be fine. Stop once you're above the bar (second screenshot). Wait for your target to show up and send a new report.

You may now proceed to the next room. The last area from where you'll have to send a report is located above a group of krogan mercenaries (first screenshot), but naturally you must wait for Joram and his bodyguard to show up. Head on towards a nearby door (second screenshot).

One of the workers will stop you in the next room and there are three ways of getting past him - you can knock him unconscious (special renegade interrupt; first screenshot), you can convince him to let you through (special paragon/renegade dialogue options) or you can keep choosing standard dialogue options until Shepard loses patience. Thankfully you won't have to worry about failing your mission because of him.

Keep heading towards a new door to trigger a series of cut-scenes. The most important decision you'll have to make is to either prevent Thane's son from completing the execution (special paragon interrupt) or allowing him to do it. You should also know that if you're playing as a renegade you may assassinate the target for him. Wait until you return to C-Sec office. Choosing a special dialogue option (paragon or renegade) will result in Thane's son receiving a lower sentence.
