So this is actually my second time playing. For some reason I don't know why I can't complete reunions, the quest where you kill Kellogg and get the cybernetic augmentor to the memory den.

First time I played I spoke to both Piper and Valentine before killing Kellog and finished the quest. This time because I was playing a second time I forgot to speak to Piper even after I killed Kellogg. Plus I've been running around with Valentine, so now when I try to speak to Piper and get them together they just ask me if I want them as a companion.

I never get the chat about the memory den and when I go to speak to Dr Amari she doesn't start the quest.

Any idea how I can solve this?
