Val has been the best friend of Fran Fine ever since elementary school, in Flushing, Queens, New York. When the show began, Val had been working at the same bridal shop as Fran; she was present when Fran was fired from her job and dumped by her ex-boyfriend, Danny Imperiali, in favor of Fran’s arch-rival, Heather Biblow.
Sometimes Val comes across as not very bright, some would say outright dimwitted, and it annoys and worries Fran. However, Fran once says jokingly that she became best friends with Val because the latter would make her look smarter. When she and Val disagree, Fran many times uses Val’s intelligence as an insult. Val will often briefly take offense, but charmingly admits that Fran is the more intelligent after calming down, which builds the friendship and camaraderie between the two.
Like Fran, Val initially has an unsuccessful love life, dating men occasionally but never settling down. At one point in time, she, Fran and Fran's sometime nemesis, C.C. Babcock bonded and swore off men for a while. At the end of the series, Val begins dating a pharmacist named Fred and was pregnant to his son. At some point during the series Val loses her job at the bridal shop and in season six Maggie's Wedding she states that she is now working at a Krispy Kreme.
Val was a bridesmaid at Fran’s wedding.
In season one it is mentioned that Val’s father is a plumber and Fran states that Val is actually very mechanical.
Towards the end of the series, Val adopts an Asian daughter named Mai and was pregnant to a child (she stated it was a son and she'd name it Henry)
Chagall’s character was named after Fran Drescher’s biological cousin named Erica Toriello.
