  2. Reach the Council Chambers
  3. Face Saren

Saren shows up and strikes a conversation with you, talking about how you should join the Reapers. If you managed to convince Saren on Virmire, he he says that it was because he couldn't stop thinking about what Commander Shepard said. Sovereign sensed Saren's hesitation, so it decided to install implants on Saren. If you convinced him on Virmire, and manage to do so again, he commits suicide. If not, you will face him again in a similar fight as the one on Virmire.

Regardless of your choice, you will face a new Saren Arterius, sporting a Husk-like look and completely controlled by Sovereign. After he is dispatched, you will be treated to the end scene, based mostly on your previous choice but also on the alignment you chose to play the game as (Paragon or Renegade)
