So I just did the quest where you go to the Memory Den in Goodneighbor and access Kellogg's brain and shit. That was a really cool quest. Really wish the character ended up doing more in the game than just being the mysterious figure who stole your kid then you go and kill, with all him really doing is just kind of taunting you while you're in the one building. Feels like he could've had a more significant role... really "sympathized" or at least kind of understood the character via the flashbacks. Thought he was pretty fleshed out...
