In the DLC 'Citadel DLC' Ashley Williams and Commander Shepard have a drinking contest at the casino bar. At that moment a Vorcha and Batarian walk over to them. This is the conversation they have. [The batarian hits Commander Shepard's arm to get his attention]. Batarian: "My friend doesn't like you Alliance types". Ashley Williams: "Listen dude, we're trying to do something here". [Commander Shepard focuses on the game again. The Batarian hits his arm once more]. Batarian: "I don't like you Alliance types either". At this point Ashley and Shepard get annoyed and beat up the Vorcha and Batarian. This is a huge reference to Star Wars. See more
