The season one finale of Syfy freshman Warehouse 13 ended on a down note with 2.23 million viewers and a 0.7/2 (rating/share) with adults 18-49 (via TVBill). That's down 24% from last week's 2.93 million and down ~30% with adults 18-49.
That's a season/series low for the show, but it will be interesting to see if its DVR viewing rises even more for this episode than usual. We won't find that out for at least a few weeks though.
But last nights ratings don't matter much. Warehouse 13 has already been renewed and will be back next summer!
