By actually introducing him in 1 or 2, or hell, even the start of 3, showing things happening with him as catalyst. Not just have a few stupid "cool" rigged fights with him as the ultimate Mary Sue and Shepard as a bumbling idiot. Actually giving him a real personality would be nice too.
He was introduced in the books though, but i agree that it comes out of nowhere if you didn't read those.
