After 30 years, they're meeting again.

The matriarch, Ami, said that it is a "profound" thing for her children to let a stranger in. Brown's youngest Rain said in the clip her worry about how Twyla will react to meeting them, saying "What if we scare her?"

What Will Tear The Family Apart

Billy can also be heard in the clip saying that they've spent their lives making the family strong and he doesn't want "this thing" to tear them apart. Whether he was referring to the past that's making a comeback in his life with his daughter Twyla will be revealed in the episode.
