When Carrie (AnnaSophia Robb) inadvertently complicates things with Sebastian (Austin Butler), she tries to fix it by taking him to Madonna’s “The Virgin Tour” launch party – but in her quest for the perfect night, only makes things worse. Despite Mouse’s (Ellen Wong) best efforts to avoid West (guest star RJ Brown), she can’t seem to deny the romantic sparks flying between them. Dorrit (Stefania Owen) turns to Donna LaDonna (Chloe Bridges) for advice about her budding love life. Meanwhile, Tom (Matt Letscher) has an awkward encounter when he spends the night somewhere new. Freema Agyeman also stars.
