Being a VI, Avina's capacity for discourse is limited; if Shepard asks for Avina's opinion on a subject, or if the Commander's questions get too politically charged, Avina says it hasn't been programmed with the parameters to answer. If Shepard tells Avina about being invited to the Council Chambers, it says that is a rare privilege; it states that it would be jealous, but that is beyond the scope of its programming.
Mass Effect Edit
After Saren Arterius launches his attack against the Citadel, Shepard's team returns to the Citadel via the Conduit and can access the Avina terminal near the elevator. Avina gives them a status report on the geth attack and lists the damage on the Presidium. At this point Avina's holographic generator seems to have been badly damaged, though it can still report what happened to the Council, as well as where Saren is headed.
Mass Effect 2 Edit
Avina is found on several terminals around the Zakera Ward. Avina will answer questions concerning the current state of the Citadel and the local points of interest found around the terminals. Avina notably states that the Citadel attacks were caused by the geth rather than Sovereign. If Shepard asks about the Reapers, Avina states that it has no information regarding the term.
If Shepard questions some of C-Sec's security measures following the original Council's death, Avina will say that C-Sec officers are coming to detain the Commander and advises them not to resist.
Mass Effect 3 Edit
Avina can be found on all levels of the Citadel. It provides information on local shops and features. Avina has different dialogue trees depending on the level of the Citadel Shepard speaks to it. This allows for specific information about the local area. However, Avina does not acknowledge the Purgatory Bar; when asked about Purgatory, it states that 'Purgatory' appears in the religious works of several species.
Mass Effect 3: CitadelEdit
Avina is also available in the Silversun Strip section of the Citadel, where it can point out the many sights and attractions in the area.
During the party, depending on options chosen, EDI may at one point be heard imitating Avina's voice, much to the amusement of (if he's present) Jacob Taylor who mentions having used Avina to find his way around.
Mass Effect: Andromeda Edit
Avina is installed aboard the Nexus and can be accessed on terminals throughout the station. As with its Milky Way incarnation, the virtual intelligence has limited capacity for discourse and can only offer information pertinent to the colonists of the Andromeda Initiative. It is tasked with briefing the Initiative's recruits about the Arks and the Nexus.
Avina's avatar in the Common Area becomes compromised by an anti-AI group on the Nexus, which they used to communicate with Pathfinder Ryder, who they secretly sent a virus to sever their connection with SAM, and let Ryder know of their leader, Knight.
