IMDB trivia says this is Ilene's last appearance, which is pretty shocking considering how abruptly she and Al broke off their relationship. There was no buildup; both of them surprised their Taylor friends with feelings they'd been having "for months", and that's it. No closure, and apparently also no "good friends" (because "good friends" still see each other sometimes, and if Ilene never appears on the show again, that means she's probably not seeing Al ever).
