Spoiler alert: Do not read on unless you've seen Episode 4 of "The Following," titled "Mad Love."

Things got personal on tonight's episode of "The Following," with the unhinged Maggie (Virginia Kull) kidnapping Ryan's (Kevin Bacon) sister in order to lure our troubled hero into a trap.

Maggie devised an ingenious way to kill Ryan, using magnets to disrupt his pacemaker, and things were looking grim until Mike (Shawn Ashmore) burst in to save the day.

HuffPost TV has an exclusive behind-the-scenes video about the making of "Mad Love," featuring star Kevin Bacon, which you can watch above. For more "Following" goodness, check out our interview with Adan Canto, who plays Paul, one third of the show's psychotic love triangle.

"The Following" airs Mondays at 9 p.m. EST on Fox.
