Ok. Strong is by far the hardest companion of make/keep happy. Everyone without enough endurance(or personal preference) to become a Cannibal is pretty much stuck doing Minutemen quests to earn his approval. And Why the Hell did you choose Lock picking to be his pet peeve? There are several quests and such that cannot be completed without at least picking a novice lock. Not to mention all the Magizines and various other loot stashed behind them.
I have a few simple fixes for Strong:
- Strong will say "Stop Fiddling, Smash!" when you pick a lock. This gave me an idea. Give Strong the ability to smash open Novice and Mission Mandated locks. It gets around a design flaw, while at the same time enhancing his character concept. "STRONG SMASH!!!!"
- Have Strong like it when you Kill certain Named individuals, Such a the Wordy Two-timing Bobbi or Named Raders or Raider leaders. Killing leaders of "Successful" human groups should earn Strong's Respect.
- Find something else for Strong to Dislike other than lock picking if you do not do #1. You made it far too commonly used for Strong to be practical for all non-cannibal Characters.
