Is Grewal planning to use Nina for a come-back?

Vanouverite Ken Gardiner raises some interesting questions about Grewal's recent decision to leave politics (here)

I don’t think Gurmant Grewal will be out of the game for long. His MP wife Nina is the ace up his sleeve and it’s time to reshuffle the deck. I predict that he will use Nina to continue networking while he plans a quick comeback.

As Mr. Gardiner points out, the idea that there is much political separation between the two is difficult to sustain: he is known to have coached her politically and (as we'll be exploring over the next few days) felt comfortable negotiating on her behalf.
