Mass Effect Disruptions
Chapter 2
Garrus Vakarian. The fangs of the Normandy. The one who ensures its weapons are at their peek at every hour, and who guards his comrades from threats too far away to see. A being who seems to be an arbiter of justice.
Look deep enough, however, and you will find a outcast, self-made. Someone who has struggled all his life with what the right course of action is. Someone who is of absolute moralities trying to live in a world of subjectivity. Of black and white in a world of gray. Despite all that he has been through, he still remains unsure of what he ought to do. Maintain as best he can his stance of immutable right and wrong, or accept the fact that such things must be flexible, that what constitutes right and wrong are themselves subjective and indeterminate?
I will help him decide.
Thinking about what Garrus' main character arc has been throughout the series, it's always been him trying to figure out what the right thing is. Even when he's the paragade ex-cop in the first Mass Effect, the fact that he's so clearly open to a Paragon Shep's viewpoint suggests he's conflicted even then. Then with Sidonis and all the hard calls he has to make as a military advisor in ME3… I'd say he's grappling right and wrong for most of the series.
