While we haven't seen much of Rob Kardashian on this season (come to think of it, we don't think we've seen him at all), we did get to HEAR him when he called Khloe during the car ride.
We would have loved to see Rob go on the fun trip with the crew, and it sounds like they wanted him there, too. "Why aren't you up here with us?" Bruce asks. Rob didn't really answer the question, though, he just sort of made a joke about Pismo and moved on with the conversation.
After they hang up, Bruce asks Khloe how he's doing being as he lives with her and she is the closest to him. "He goes up and down, you know," Khloe answers. "That's Rob."
Obviously, Rob was missed on the trip, but Khloe, Scott and Bruce seemed to have a pretty good time with just the three of them and after all of Scott's partying we saw on the episode, it was good to see him having some good, clean fun with the fam.
Editor's Note: Per Jenner's stated preference, Cambio will continue to refer to Bruce using male pronouns until he indicates otherwise.
