I've been advised to look up a robot bloodhound 'Detective' ie 'Dick' named Nick Valentine.
I'll just call him Dick Nick for short.
Barabbas is not a big fan of the po-po, even if he has been going soft the past 75 levels or so.
He's a get-along, go-along kinda guy, I am planning his great sense of festering disillusionment to grip him upon arrival in Nuka World, so be patient !!
I will manage somehow to be a big meanie yet !!
