Kelly Goodweather

Kelly Goodweather is Ephraim Goodweather's ex-wife and a major antagonist of FX TV series ''The Strain. ''

She took on a life after custody of their son, Zach, but ignores her husband's warnings about the Vampire contagion. She is turned into a Vampire (Strigoi) by her boyfriend, Matt, after the infection spreads throughout her body and becomes the Master's thrall,  fully under his dominion even though her metamorphosis is not yet complete.

PAST
Kelly was a public school teacher and a fiercely protective mother. She lived with her boyfriend, Matt. Although it's pretty obvious she still loves "Eph", the fact that he has continually put his job ahead of her and their son is the reason she has moved on.

Season 1
She became infected after a blood worm from Matt went through her eye. Her infection progresses quickly as she walks through New York, barely able to think coherently. She mistakenly goes to pick up her son in daycare, but he was already picked up by her friend Diane whom Kelly visits and infects. Afterwards she is called by The Master and becomes his thrall, fully under his dominion even though her metamorphosis is not yet complete.

After the group of vampire hunters managed to drive off The Master, Ephraim and Zach go to their home to collect inhaler for Zach's asthma. However, it turns out Zach only wanted a family picture. Suddenly they hear a noise by the window and an infected Kelly enters. Zach tries to go to his turned mother but Eph restrains him while shooting Kelly in her shoulder, forcing her to leave. Abraham Setrakian tells them The Master will most likely use Kelly to track them down, using Kelly's love for Zach to his advantage.
