I wanted to do the whole thing without Paul getting involved (I told him I'd talk to Cooke alone), but the game bugged out when we ambushed the deal and Paul came anyway despite not knowing of it and he was bugged out with no dialogue. So much for taking different approaches with that quest.
So I had to bring Paul with me and I found him rather annoying by the time we were all in on ambushing the deal, especially when he starts whining about getting a share, like the filthy pleb did anything besides not please his wife, pfffh. Cooke though was a cool cat. Killed Trish myself, as I didn't need to know the password.
In the aftermath, I told Latimer his son had it coming getting into that business and he accepted my apology. Told Cooke's daughter I don't know where he went. And Paul took over for Cooke, but for some reason ended up dead and found his body where the deal took place. Must have been some weird bug, but I just went with it. He wanted to live the chem dealing life and ended up dead...somehow.
