User blog comment:James12708/Why Exactly is Sheperd on Earth if Arrival Wasn't Completed/@comment-4737548-20121206165858

The debate ive seen multiple times now is whether or not arrival is cannon. The argument of "because anderson said so" isnt an end all, since he also says shepard did it. I agree that the comic shouldnt have established one as cannon storyline, but there isnt any solid reasoning that shepard skipping is cannon either. Perhaps there should be some kind of discussion of this.
