The quest is still active. How you want to proceed, then, is up to you. There are a number of people, especially in Rivet City, you can ask about the android, and you will eventually get a particular clue about someone -- also in Rivet City -- who can tell you more and stretches the quest out a bit more. Or, you can side with the Railroad, turn in the part you already have in your inventory, and end the quest entirely.
Thanks so much!!!
No I don't want to end the quest.I want to poke around and figure it out.
It's good to know I haven't done anything to ruin it.I don't care how long it takes me.
I really am loving how this game is put together.
Thankyou all for your great help.
