At the start of season 3, Karen is still refusing to believe that Matt is dead. To that end, she is hyperfixating on the Midland Circle collapse to a degree that Ellison begins to take notice, and is paying rent on Matt's apartment. Ellison and his wife also try to set Karen up for a date with his nephew Jason, with minimal success. Her belief that Matt is still alive is piqued when Ellison sends her to interview Neda Kazemi, a socialite who was attacked by men working for Fisk, and learns that Matt fought off the assailants.
