The character also becomes romantically involved in the series with two other housewives, Edie Britt (Nicollette Sheridan) and Bree Van De Kamp (Marcia Cross), both of whom he gets engaged to.

Karl dies in Season 6, Episode 11 after injuries sustained when a plane crashes into Wisteria Lane during the Christmas Festival.

According to Cherry, casting the role of Karl was difficult because he "wanted a guy that was nice looking and seemed like he would have been married to Teri, but was also someone you wouldn't like.

[7][8] Julie's mother burned down all the bridges that connected her with her husband: sports awards, golf clubs and shoes.

[9] In the season one episode "Move On", Karl ends his relationship with Brandi and asks Susan for a second chance, but she declines because of her commitment to Mike Delfino.

[15] Karl appears only in the episode "Children and Art" to play the bad cop for Julie and Austin McCann, who have started dating.

This backfires when he gets mad at Susan for dating Ian Hainsworth, a married English man whose wife is in a coma.

Karl returns when Susan meets him at a Lamaze class as his pregnant new wife, Marissa (played by Sunny Mabrey), is there; Mike is not there as he was receiving his 30 days chip.

Susan, concerned, approaches Karl, and it turns out that Marissa has left them because she could not handle being a mother, leaving him to raise Evan by himself.

[17] Bree later hires Karl as her divorce lawyer, and he helps her stage a fake burglary of her house to hide assets that she does not want Orson to have access to.

The fight is brought to an end when the pilot of the plane Karl hired suffers a fatal heart attack at the controls, and subsequently crash-lands into the party, smashing straight into the workshop.

Richard Burgi makes one last, uncredited appearance as Karl in the series finale, "Finishing the Hat", as one of the ghosts that watch Susan and her family leave Wisteria Lane.
