Things definitely seem awesome and baby-centered for Blac Chyna and Rob Kardashian now, but that apparently hasn't always been the case. In a fresh clip from this Sunday's mid-season finale of the gripping E! docuseries Keeping Up With the Kardashians, the family discusses a recent fight that's left Rob feeling less-than-enthused about the future.

"So I'm trying to find Rob," Khloé Kardashian told Kris Jenner and Kim Kardashian in the clip. "I've called him, texted him. He's not responding." When Kris clarified that Rob wasn't currently at Chyna's house, Khloé expressed her concern and asked how much longer the seemingly big fight was going to last.

"I don't know," Kris said, referencing Rob's previous struggles. "But I talked to Chyna, and it scared me because it was everything that we experienced with him. She was experiencing the same thing. She wrote me last night and she said, 'Can I see you tomorrow? I just really need to talk to you.'"

The main concern for the family, Khloé said, was making sure Rob was handling his disagreement with Chyna in a healthy way. "I know when my brother, hurts how badly he does hurt," she told Kris and Kim. "The more they're fighting and the longer things are bothering him, the more depressed he gets. He'll go into hiding again, go missing. I don't want Rob to live that life anymore."

All is well in the land of ChyRo now, though, as Chyna was unveiled Monday as the cover star for the new issue of Paper magazine, and the couple's own E! docuseries has been teasing its highly anticipated Sept. 11 premiere. "I'm excited about fans getting to know me as a person and not as a thing or a face," Chyna told Paper. "I hope when people think about Blac Chyna, they think of a mogul and entrepreneur, a mother, and a badass bitch."
