The Nexus, I'd guess. Then maybe another on Earth linking to the Hyperion, one on Palaven to the Turian ark, and so on. So I guess another possibility is that the MW terminals just got blown the fuck up.
I'd have to double check the timeline, but Wrex would be the de-facto leader of the Krogan by the time the mission launched for sure, and Liara might be the Shadow Broker at that point, so both could merit references.
Even then, Liara being the Shadow Broker is supposed to be a secret outside of the Normandy's team, so i'm not sure how they could even make that work. Or why would someone even talk about the Shadow Broker in Andromeda lol.
