Game of Thrones begins....

Considering Bran is busy beyond the wall, I think it more likely Jon was inhabiting the wolf.

That's my guess as well, and I think that it is going to be the explanation for why Jon doesn't suffer the memory and personality loss that Dondarrion did.

[Admiral Yi]

I think that if Jon had super Vegan warg powers they would have foreshadowed it at some point.

The pooch stirring I just interpreted as heightened sensitivity.

[Martinus]

I agree with Yi.

[Hamilcar]

At least in the books, all the Stark children are powerful wargs.

Jon is a Targ.

Eh?  I read the books and I don't remember that.

[Zanza]

And a Stark.

Jon is a Targ.

While most Targs are remarkably inbred, Jon isn't

Hence the lack of silver hair.

[Martinus]

Anyways, on the show none of the Starks other than Brann give any indication of being wargs.

Arya "wargs" into her dire wolf in her dreams. But it's different from Bran or the wildlings that warg while being awake.

Arya wargs Nymeria, and her cat.
Robb clearly wargs Grey Wind.
Jon wargs Ghost.
Sansa doesn't really show any warging ability, likely because Lady is dead.

IIRC GRRM Himself confirmed that they are all wargs.

[crazy canuck]

I maintain that Jon Snow's resurrection was a misdirection. Melisandre didn't do anything. Bran is warging him.

There was something going on with the Dire Wolf in that scene.  I think you are probably correct.  But Melisandre is going to get/take all the credit.  Setting up a confrontation between the God of Light and the Old Gods - or at least their followers?

Considering Bran is busy beyond the wall, I think it more likely Jon was inhabiting the wolf.

Yeah, as I said a before that episode.  That is what I think was happening.  We don't know the limits of the power of the three eyed crow though.  I am not sure there is much of a geographical limitation - especially at a location that is so close.

[Josquius]

Don't forget bran can travel in time as well as space. Not impossible it could be a future bran.
Though I doubt it.
Could be something with mels magic combining with the wolf warging. ... but the way I saw it was just that the wolf detected Jon had come back to life and moved to investigate

I'm not sure what you mean.  In the books, all the Stark children have warg abilities, especially with their dire wolves.  I think that there has been a lot of foreshadowing of warging into animals and surviving death, and I can't think of a reason they would spend screen time on that if it weren't going to be used (e.g. to have Jon's personality survive death intact).

[The Minsky Moment]

  Martin has said that the starting point for his work was the War of the Roses, which took place in late medieval England..

Which is what the made the narrative interesting and stand out from the usual.

But both books and show have increasingly increased emphasis on the fantasy aspect (dragons, magic, faceless men, warging, dead raising, snow zombies, etc) while - as you point out - eliminating the more interesting savvy and brutally realist political operators.
