I think he wasn't that much elaborate in his reasoning as he can be on other topics. Also, if let's say Pot was a vig, he'd destroy his ability, causing him to actually, if Town, never be self resolvable? Or any other ability.
Also, he suspected strongly Reloaded during night, to believing his confusion between having a kill ability and protect ability. Reloaded wasn't self resolving. Would be a very natural choice for this actions from Cryo perspective.
Also, I told him I strongly TR Naomi, and Cryo said he trusts me the most. I understand that he doesn't have to sheep me and lock her town , but shouldn't that at least a bit not warrant a PR usage there?

@Jan - you think this Watcher usage is very clearing for Flower?
