"Because you're sensitive!" Khloe snaps back. "You have to worry about Rob, and how you can be strong and better for you, and now your baby."
"My plan is not to have a kid with somebody and not be with the person," Rob concedes. "That's just bizarre to me."
"I know Rob and Chyna have a long way to go, but I'm really happy that they are working things out. Relationships are hard no matter what, and as long as Rob is trying, and starts really engaging and communicating, that’s all I could ask for," Khloe says after her conversation with her brother. "But he has to figure it out, and this is like baby steps to his life."
