Polar bears are one of nature's most determined and efficient hunters. And deadly. And exactly as xfkirsten said above, the gene pool has to be enlarged, or we'll get inbreeding problems.

Shippers drive me crazy. I'm a Shep/Weir shipper -- McKay/Sheppard gives me hives and makes me nauseous -- but if someone else thinks its the best thing since Starsky and Hutch, who am I to piss on their parade? But shippers are nuts. Sanity. I have work to drive me crazy. I don't need fandom trying to help. Seriously.

Remember that nobody ever went broke underestimating the taste of the American public, God help us all.
