claims to his mother that he has changed and is now a plumber. Dot ends up believing Nick when he introduces her to his six-year-old daughter Dotty (Molly Conlin), thus disclosing that his mother now has a granddaughter. Although Dot promptly bonds with Dotty, she continues to remain apprehensive towards Nick and quickly learns that he is once again exploiting their reconciliation for her.
