Even though Khloe says that Scott's house has a "serene" view where "you get the outside so you never feel depressed," Scott says he's "still depressed."
"How are you depressed?" Khloe asks.
"Because I'm single and I live here by myself," Scott says. "I fell in love with the house that I'm in until I actually moved in and realized that it's way way way too big for a single human being living alone. You know I'm sure a lot of people wish these were their problems, but it's a drop lonely living alone in a big house."

So I walked in on him with Blac Chyna at my house, there was alcohol everywhere, he's having the time of his life. I don't need this s--t, don't you dare make me feel uncomfortable in my own home."
Khloe then says, "I don't really care who Rob dates but having Chyna over at my house without my knowledge is disrespectful, why can't he be honest with me and communicate? Because Robert knows Chyna's Tyga's ex-girlfriend and I just don't want that drama in my personal space."

I said, 'You jumped that ship as soon as you did Diane Sawyer and you like attacked my mom!' Instead tells me to 'get a life' and to 'shut up' and all this. I'm like, 'You shut up and you get a f--king life.'"
