Hello,

There is a bug with Silver Shroud quest.

At the end, when he is kidnapped, ii gone to the hospital with Hanckok, i saved him, but he is stuck in the hospital, and never return to Goodneighboor...

I don't know if it is because i killed the protectrons (i didn't remember killed them)

I don't know if it is because i was with Hancock

I don't know if it is because i talked to him about the armor in the hospital...

There is some possible fix (and some possible ways to avoid this problem) on Wikia

http://fallout.wikia.com/wiki/The_Silver_Shroud

I think I had read that it might be talking to him about the armor while still "out in the field". I am not sure how to fix him, unfortunately, if that IS the case.

that is the same for me, i read this after doing the rescue mission...
I am waiting for a patch, of a fix...
