David Hewlett's Sister to Guest on SGA

Gateworld reports here that Kate Hewlett, David’s sister and a professional actress, will play McKay’s sister in the Atlantis Season 3 episode “McKay and Mrs. Miller”. This is welcome news to Rodney/David fans and a great pay-off to David requesting in a Season 1 script that a reference to McKay having a brother be changed to a sister, to match his real life.
