After a 13 year absence, a former star is coming back from the dead and returning to the show. Give her one obligatory flashback, a snarky conversation with her onetime rival, and pack her off to Switzerland with her daughter. A romantic beach, reminiscent of a previous adventure. Trapped in a cabin on a snowy mountain, thinking they'll freeze to death. Trapped in the catacombs with a dead body, thinking they'll suffocate.

To keep the geometric thing going, you need another one. This time, she'll be a rival for the husband instead of the ex-lover. The husband talks a beautiful stranger out of jumping off a bridge, and is immediately drawn to her. Years ago, the husband seduced the woman with the sole purpose of acquiring her company. He succeeded, leaving her bereft and bankrupt.
