This mission will start after you meet the Council for the first time. It serves as a subquest for the larger objective Citadel: Expose Saren and runs in parallel with Citadel: Garrus, another way of getting the intel you need. We recommend seeking out Garrus before Wrex.
Talk to Barla Von
If you asked Anderson about “Other leads.” after meeting with the Council, you’ll have the mission Citadel: Shadow Broker instead of Citadel: Wrex, which just adds a frankly unnecessary first step to the latter quest. If you have it, however, find Barla Von in the Financial District of the Presidium and ask for information. Surprisingly, you’ll get the information you need without having to haggle, as your interests and those of the Shadow Broker happen to align. Deplete Barla Von’s dialog options and you’ll get some Codex Entries, after which you’ll need to find Wrex at C-Sec Academy.

Wrex at Chora’s Den
If you didn’t ask Anderson about “Other leads.”, you’ll need to travel to Chora’s Den to get this quest officially started. You can make your way to the Wards on foot, or just use the Citadel Rapid Transit terminal south of the Council Chambers to warp directly to Chora’s Den. Head through the doorway to the area outside of Chora’s Den and you’ll be attacked by two Assassins, who are more dangerous combatants than any you’ve faced thus far.
They’ll have health regeneration in basically every difficulty, and may use other abilities if you’re playing above normal - a white health bar indicates an enemy is using Immunity, which means you’re not doing damage until that wears off. Try to keep them at a distance, where their shotguns will be less powerful and if one gets clever and rounds the corner, concentrate fire on them. There’s only two of them, so focusing your abilities on one should put him down fairly quickly.
After they’re defeated, continue on into Chora’s Den. Head around to the southwestern end of the circular bar (roughly 8 o’clock) and you’ll witness Wrex threatening Fist through the intermediary of a krogan bouncer. Wrex will leave after that and you’ll need to seek him out at C-Sec Academy.

Wrex at C-Sec Academy
After meeting Wrex at Chora’s Den or talking to Barla Von, you’ll be able to find Wrex at C-Sec Academy,.the elevator to which is on the Presidium, near the Embassies. Approach Wrex and you’ll find him being chastised by some C-Sec officers, after which Wrex will turn his attention to you.
You’ll be told about the Fist-Saren connection, and once again, it seems your goals will align with those of this alien’s. Wrex offers a deal: he joins up and you cooperate to take down Fist. Wrex gets to kill Fist, you get the data you need to expose Saren, everybody wins… except the bad guys. There’s no good reason not to accept, after which Garrus will be brought up. You can advocate in favor of recruiting him or decline, but it doesn’t matter much either way - Garrus can be found at the Med Clinic on the Wards.
