Would Dana Plato still be alive?

If she had crossed-over to "The Facts of Life" instead of staying on "Diff'rent Strokes"?

"A spin-off of Diff'rent Strokes, the series featured the Drummonds' former housekeeper, Edna Garrett (Charlotte Rae) becoming the housemother of a dormitory at Eastland School, a private all-girls school. The girls in her care included spoiled rich girl Blair Warner (Lisa Whelchel); the youngest, gossipy Dorothy "Tootie" Ramsey (Kim Fields); and impressionable Natalie Green (Mindy Cohn).

The pilot for the show originally aired as the last episode of Diff'rent Strokes' first season and was called "The Girls' School (aka Garrett's Girls)." The plotline for the pilot had Kimberly Drummond (Dana Plato) requesting that Mrs. Garrett help her sew costumes for a student play at East Lake School for Girls, the school Kimberly attended in upstate New York, as her dorm's housemother had recently quit. Mrs. Garrett agrees to help, puts on a successful play, and also solves a problem for Nancy. Mrs. Garrett is asked to stay on as the new housemother but states she would rather remain working for the Drummonds at the end of the pilot.

Following the pilot, the name of the school was changed to Eastland and characters were replaced, with Natalie, Cindy (Julie Anne Haddock), and Mr. Bradley becoming part of the main group featured. Although Kimberly Drummond is featured as a student at East Lake, her character did not cross over to the spinoff series with Mrs. Garrett."
