Lol I'm nitpicking but I'm saying you shouldn't have said that at all, during the ISO I got to your wall and I had to stop and read it twice because the construction is more assertive then the wishy-washy EHHHH I don't think Zack could be scum with GH. Also you weren't implying "might" you were implying "not likely".
I think it's clearer if you understand the GH ISO on why GH is scummy as separate from, though informing, the interaction analysis with Zack.

I don't know how to resolve Slaan; I've read his responses better than you or Pizza, but he may or may not be mechanically compromised.
