While attending Friday's 49th annual Daytime Emmy Awards, the GH cast opened up to about how they've been there for the one-time costars and former couple amid this tough period in their lives. (Jack, 62, and Kristina, 59, were previously married from 1993–2006 and also share 31-year-old son Peter.)
"She is remarkably strong and she's an exemplary mother," Nancy Lee Grahn, who has been in contact with Kristina, told Entertainment Tonight. "It was a very challenging to have a son that has an addiction. That is a disease."
"They both handle it every well, but Kristina I admire her very much and she's doing really well, under the circumstances," Grahn continued. "Very strong."
Kelly Monaco empathized with the Wagners, sharing that she was able to count on the General Hospital crew for support after she went through her own loss year.
"I had a similar experience in November with my best friend, and the GH cast was amazing," said the actress. "It's a family, and the same grace has been extended to Kristina and Jack. I have chills talking about it."
Added Monaco, "My heart goes out to them because I know exactly what they're feeling. It's tragic. And I hope more people are aware of the epidemic that's going — that's been going on — for decades."

Laura Wright said Kristina hasn't returned to work just yet — but the cast "will be there with open arms" when she does. Additionally, Cynthia Watros pointed out that "there's no way to lessen the pain but just be there when they need us."
Jack and Kristina's son Harrison was found dead in a parking lot on June 6. He was 27.
Two days later, a spokesperson for the L.A. Coroner's Office said they were still investigating the details of Harrison's death.
"Cause of death is deferred," the spokesperson confirmed to PEOPLE. "Deferred means that after an autopsy, a cause of death has not been determined and the medical examiner is requesting more investigation into the death, including additional studies."
"Once the tests/studies come back, the doctor evaluates the case again and makes the cause of death determination," the statement concludes.

Jack and Kristina have since created The Harrison Wagner Scholarship Fund in honor of their late son.
"He has left behind many men and family members who loved him deeply," a statement on the scholarship's website read. "We are heartbroken that he ultimately lost his battle with addiction and we hope that Harrison's memory will live on through this scholarship and will help other young men get help for their addiction that would not otherwise be able to afford it."
