So how old is Kyla supposed to be?
It's a school reunion. The songs they were playing were all 25-30 years old. Unless it was an elementary school reunion, that means Kyla is supposed to be in her late 40s. The actress obviously isn't that old. She'd have been listening to, I don't know, Chumbawumba when she was in high school.
