He's a Charles Xavier like prodigy, his Warging seems like second nature, a sixth sense almost. In the series he might only be the only Stark to have warging abilities even.
I'm not sure that's true. There's a theory going around the Robb warged into Grey Wind - his last thoughts and words were of the direwolf. As he died, we cut to Grey Wind who suddenly is trying to get out of the cage and eyeing the Freys with murderous intent. As Grey Wind is killed, there is a moment as the direwolf's eyes stare directly into Arya's, and it almost looks like recognition.
Of course, you're not wrong. Bran might be the only one to have warging abilities, not have had.
