**POSSIBLE SPOILERS**
I've searched and searched for an answer to this glitch in the game. The only fixes I have seen are where people are able to recruit Hancock as a companion and talking to him as the Silver Shroud through the Talk option when addressing him.
However, my problem seems to be worse than that; I cannot even recruit him as I don't get the option! The only two things he says to me are shouldn't I see to another ghoul (Bobbi, who I killed) and about some group of enemies (I think, can't remember as at work at the moment) down in 'Southy', I think he is saying. I have completed Pickman Gallery as some have suggested but this has made no difference to my issue.
It's extremely annoying. My previous save before denying Hancock as my companion is approximately 3 hours previous to my current progress and I don't think I have the energy to do it all over again collecting weapons, dropping this, dropping that, crafting this, crafting that etc. I enjoy the game, but only enjoy what is new, not what I did hours previous!
I hate having unfinished quests, and I also have the Silver Shroud suit and hat taking up valuable weight in my inventory. I cannot drop it as it says I cannot drop quest items!
If anyone has a workaround this issue without being able to recruit Hancock as a companion, please do share. If not, then I really hope Bethesda picks up on this and issues a fix to at least get Hancock as my companion so I can talk to him as the Silver Shroud via the Talk option. I was thoroughly enjoying this mission but have been let down by it at the very end
Many thanks in advance.
