[Kill] Bardothren
Chances he found a white-walker just after bluffing he had found one seems too too good to be true. Changed my mind :) Lets save Gimme.
Let's not repeat Joffrey, where we wasted Dany's ability.
WaIt, now that I look back on things, I'm almost certain Bardothren is Bran Stark. I didn't even catch this before, but the grayscale ability targets a specific player, not a specific character. The chances are pretty high that Orpheus would attack the player that got him killed (I.e. Bardothren), so Bardothren = Bran Stark, it seems.
The only question is...is he telling the truth about GP being a wight? Or is GP just someone from a rival house?
Not disregarding what you said, but that's already been established. And I agree with your question, could Bard just be helping the Stark House by targeting GP or is he actually trying to help all of Westeros?
