Peace in our time: It could really be a possibility. Or at least, if this recent brunch meeting between Rob Kardashian and new fiancée Blac Chyna with his sister, Kim.

The trio hit up comfort food emporium Nate & Al's for some carbs and happy-talking, according to E! News, and to hear a source on the scene tell it, everything was just oh so very nice. "Kim and them were just sitting at a booth and they looked like they were having a good time," the source says. "They were talking directly to each other, not looking away or anything, so they were engaged in a conversation, all of them. Everyone seemed happy and they were really nice."

So there's that.
