First off, in case you're not aware of the good news, The Strain has been renewed for Season 2.
I know many people don't jump into new television shows right away out of fear of cancelation. Well, The Strain will continue next summer so if you're not watching yet, get on that ASAP. This series will be around for a long time.
The Strain Season 1 Episode 7 gave us some fascinating insight into the Setrakian/Eichhorst relationship.
We also met an interesting new soldier in the war against The Master.
