On tonight's episode of Keeping Up With the Kardashians, the family vacation in paradise quickly turns into the vacation from Hell when Kendall Jenner and Kylie Jenner disappear without a trace, in addition to a confrontation between Khloé Kardashian and Kim Kardashian that almost results in Khloé going home!
During the family dinner, Kim has a mini freakout when she discovers a lizard on Brandon Jenner's back!
The next day, Kim attempts to finish her sultry photo shoot that was previously interrupted by Brody Jenner when he walked in on Kim while she was practically naked!
Brandon does his best modeling impression by trying on Kim's sunglasses!
At breakfast the next day, Kris notices that Kendall and Kylie are missing from the table. Khloé goes to their room to find that they are gone!
After calling their phones and getting the voicemail, Kris and Bruce Jenner start to worry and argue over what happened to their youngest daughters. Kris feels that Bruce is blaming her for everything, so she comes up with the idea of the family going out in two groups to search for the girls.
Brody is the only one who doesn't join the family as they pile into two vans to find his sisters because he thinks they are simply playing a trick on everyone!
Khloé, who is already irritated with the fact that Rob Kardashian abandoned the trip, is not amused:
After stopping by several hotels and stores, the family finally gets a lead when a local taxi stand informs them that the Kylie and Kendall were spotted catching a cab into town.
Then out of nowhere, Khloé gets a text from her sisters, who send her a picture of themselves on the beach!
Khloé and Kim head towards the beach to find them, while Bruce and Kris stay back and bicker in the van.
Kendall and Kylie keep texting pictures of themselves to their older sister, and after playing the hunting game for several hours, Khloé and Kim finally find their younger sisters at a massage parlor!
Kendall and Kylie explain that they just needed some time away from their mom. When Kris hears the news she is relieved, but she wants to see her daughters in person for peace of mind.
After finally locating Kendall and Kylie, Kris gives both of them a hug! But the girls still have to explain themselves to Bruce...
Kendall tries to explain her reasoning behind her and Kylie's actions:
The next day, the family charters a boat and heads out to sea for some sun and relaxation!
Leah starts to tease Brody about having a crush on Kim, which he denies. Then at lunch, Kris teases him about having a crush on Kim since they were little kids.
But everyone is in for the surprise of a lifetime when they find out that Brandon and Kim shared a kiss back in the day.
See the crazy moment!
Then the family goes canoeing through some beautiful caves, although Kris and Bruce's continual arguing gets on everyone's nerves.
Despite their disagreement, Kris does admit that Bruce has some good ideas and she is glad they came to this beautiful spot that he suggested.
Khloé, on the other hand, is still bummed because she wishes that Rob could be there to share the experience with them.
Back on the boat, Kim catches Brandon pointing at her while laughing at Brody. She then decides to get in on the joke and tease her stepbrother for fun.
Next up, it's photo shoot time!
Kim tries to invite Brody to join her for a picture, but he gets shy and goes downstairs. Brandon then asks Khloé how Rob is doing, and she says that he is constantly depressed and never leaves the house.
Kim thinks that Khloé is trying to take responsibility for all of Rob's problems, and in return Khloé points out that Kim is being close-minded.
Khloé has an emotional moment with her stepbrother when she talks about how she always feels guilty for Rob. Brody tries to offer some encouraging words by telling her that she shouldn't feel bad.
Back at the resort, Brody has a plan to get revenge on Kim! But he needs Brandon and Leah's help...
As soon as Kim walks into her room, this is what she sees:
A shocked Kim snaps a picture of Brody and threatens to blackmail him before he runs out of the room, leaving his clothes behind!
While at dinner, Kris and Bruce step away to discuss how their youngest daughters didn't believe that their parents could still love each other and be good friends despite their separation. They realize they still have some work to do...
Back at the table, Kris makes a nice toast and mentions that no matter what the family goes through, they always love each other at the end of the day.
Then Khloé reveals that she has a flight on hold because she's thinking about returning home.
When Kim asks Khloé why she would bother coming all the way out there only to go back so soon, Khloé snaps at her:
Kim's shocking response:
Later, Khloé and Kylie have a heart-to-heart by themselves and Khloé reveals that she almost punched Kim.
The next morning, Kris and Kim discuss what happened between Kim and Khloé the night before. Kris admits that like Khloé, she also worries about everyone all the time and is always stressed, so she understands what Khloé is is going through.
Unable to control herself any longer, Kris breaks into tears.
See the emotional moment!
Kim knows how close Rob and Khloé are and realizes how hard it must be on her sister, who is also dealing with her separation from Lamar.
While Kim understands why Khloé is trying to help Rob, she also thinks that Khloé needs to keep an important thing in mind:
