Reunite the Coffee Beans without skill check or having a psychopath in your squad (spoiler)

Do the wig quest to get the Ma Baxter's Argument Invalidator before talking to the Grandma. After you get the shotgun, talk to the Grandma and give the shotgun to her.

Interesting. Might try that next time.
Forgot to reunite the CB's this time but at least none of them got killed during N-Night. So the Kamikazee Kayla lives on.
I missed the Pulp Fiction - 'I'll execute every last MF one of you!!' shout though.
