Louie plans to his girlfriend, Judy (a blind woman introduced to him earlier this season by Latka & Simka), but before he can do it, Judy tells him that she's having an operation to get her sight back. Louie then gets cold feet, worried that she'll reject him because of his looks. Alex talks Louie through his insecurities and Louie goes to the hospital to support Judy after her surgery. It turns out the surgery is a success and she still loves Louie after seeing him. Louie is thrilled and decides to buy her a real diamond before he proposes (since she can now see and may be able to tell the difference). (thetvdb.com)
