About Karen[]

When Mrs. Roper accuses Mr. Roper of showing his visiting lovely redheaded niece Karen a very boring time, Roper decides to introduce Karen to Jack, assuming that, in thinking that Jack is "gay", he wouldn't "try anything with her." When Jack meets Karen, he is surprised to find she is so beautiful; he had thought she'd look like Mr. Roper. He asks Karen out and tells Janet and Chrissy he'll be back in time for a birthday party he helped plan for Janet, also for which he even baked a cake. When he is late, Janet and Chrissy become angry, then realize that they are actually jealous of Karen, who was smitten with Jack from the moment she laid eyes on him!

When Jack, who tries to behave like a "perfect gentleman" in front of Mr. Roper upon meeting Karen, he tries to continue that act in hopes of not tipping off the fact that he's not gay, Karen can see right through his ruse, and wonders why he hadn't tried anything, as she amorously makes an advance upon him, but helps him maintain his deception upon her Uncle Stanley, so he won't get evicted!
