Kim is obsessed with Kylie's tumblr. She goes on her tumblr just to see what's cool and hip. Kylie shows up at a premiere in Kim's clothes, which angers Kim because Kylie won't answer her texts. Kim decides to go in Kylie's closet to get all of the clothes that belong to her.
Scott continues the "Todd Kranes" phone prank on Kris. Kourtney decides to call the real Todd Kranes and confess that Scott has been posing as him in order to prank call Kris. They decide to have Todd show up at the house. When he arrives at the house, the guards call, knowing that Kris will pick up the phone. She opens the door and Todd shows up. Scott then does the Todd Kranes voice and she figures out it was him pranking her all this time.
Bruce gets a phone call from his mother, Ester, which prompts him to go visit her. He asks Kris to come with him, but she doesn't want to go because her and Ester don't get along. Bruce suggests to fly Ester to the family home. When Ester gets to California, Bruce tells to Ester to have a private heart to heart with Kris. When Ester arrives at the house, Kris is reluctant to talk to her. Eventually they engage in some small talk during dinner. Kris has to leave the dinner late, before Ester gets a chance to have a private conversation with her. The next day Bruce picks up Ester from her hotel and takes her back to the family house. Ester apologizes to Kris for not being close to her.
