you are an ordinary settler who lives in the wastelands of Boston, at some point you caught a radio signal that the settlement was accepting people and you went there

when you got there you met two robots arguing loudly. One looks like a regular assaultron but with gray skin color, and the other looks like a assaultron with a robobrain head

Ada: protection needs to be placed here, not there!

Jezebel: no, it needs to be there!

suddenly they notice you

Ada and Jezebel: Hello, traveler!
