There was a mix-up in the dates of when Tahmoh will be appearing in Bomb Girls. It turns out he was in episodes 8 (Fifth Column) and 9 (Something Fierce). Both episodes are now available to watch online if you're in Canada. And here's another promo pic that Global TV released.
If you're in the US, Lifetime TV is showing the world premiere of Stalkers tonight, April 13 at 8/7pm Central. Tahmoh stars in the Lifetime Original Movie with Jodi Lyn O'Keefe and Mena Suvari.
