Jack Ewing[1] is a character that appeared in the popular American television series Dallas, played by Dack Rambo from 1985 to 1987.
During this time Jack also briefly dated Jenna Wade who became mentally unstable due to Bobby's death which ended the romantic part of their relationship.
Angelica, with the help of Jack's cousin J.R., persuaded him to pose as Dimitri at a conference in Martinique to convince the company's investors that business was running normally.
In 1986, Jack's former wife, April Stevens, turned up in Dallas to make a claim to half of his 10% of Ewing Oil.
April proved that, during their divorce hearing, the judge granted her half of Jack's future income.
