Both Stephanie and Brooke appeared on the soap from the very beginning, when it premiered in 1987.
Brooke and Stephanie’s feud only grew from there.
Eric had another affair, but this time with Beth Logan’s daughter, Brooke Logan.

After her divorce from Eric, Stephanie had a stroke that caused her significant memory loss.
They renewed their friendship, but Eric had already moved on and married Sheila Carter (Kimberlin Brown).
Stephanie told Brooke to get out of the country and attempted to gain custody of Bridget and Rick.

She pestered Brooke to leave the couple alone, but the blonde wouldn’t listen.
Their arguments culminated in a fight during Brooke’s reveal of her new lingerie line at Forrester Creations.
Things got even worse when Brooke and Thorne announced they were engaged, causing Stephanie to have a stroke.

After that health scare, Brooke tried to mend fences and gifted Stephanie a photo album documenting her life.
When Ridge was presumed dead, Stephanie and Brooke grew even closer, commiserating over their shared loss.
However, the feud returned when Ridge was found alive and wanted to get back with Brooke.

Stephanie faked a heart attack and asked Ridge to reunite with Taylor, which he did.
Angered and offended, Brooke turned the gun on Stephanie and tried to shoot her, but she missed.
It didn’t work, and Brooke married Nick anyway.

Stephanie refused to receive treatment or tell her family and friends about her diagnosis.
Instead, she enlisted Brooke to help her fulfill every item on her bucket list.
However, Stephanie couldn’t stop her meddling ways altogether.

Sadly, Stephanie’s lung cancer returned, and this time it was terminal.
Apparently, Brooke and Stephanie’s feud continues, even beyond the grave.
