5 Reasons You're Wrong About Dragon Age 2's Story
3. Companions Act Independently
In the first Dragon Age, and in Dragon Age Inquisition, the companions are yours to command and control, both in terms of gameplay and combat, as well as decisions they ultimately make in the story.
In Inquisition, Leliana has been hardened by a cruel world into a more extreme assassin, less forgiving of others and more willing to kill. Unless, of course, you scold her once or twice, then she's completely back to normal. Makes it easy, right?
However, in DA2, things are not so simple. Fenris was mistreated by mages in the worst way possible, all his life. While you can make him ease up a tiny bit by the endgame (i.e. convince him that genocide is not a good solution to interpersonal conflicts) that baggage isn't going to go away.
Characters operate outside of your control in-story, driven by their own beliefs and morals, and more often than not, those beliefs and morals will clash with yours. For example, convincing Fenris not to murder his traitorous sister in Act 3 is technically the right thing to do, he will even admit as much later. But this choice earns you rivalry points with him all the same.
In a tragedy, there is always a disconnect between characters, even the closest friends and family. And the actions of the characters may seem like the right call to them, but will screw others over (usually the protagonist) later down the line.
