If i had a Hos of the bear and i reveal Fortified position, my host leaves? thanks.

Potato salad.

I believe the answer to this would be "No." Fortified position is a constant effect that would be active BEFORE the Host's effect could be used, since, by the time initiative is counted, Host of the Bear's text is already blank.

Yes. There's not much more to elaborate other than to remember that his text is blank as soon as you reveal the plot, so, when you have the initiative low enough to discard him, his text is blank.
