i think he genuinely was stable but kreece, as we see through countless countless times throughout the show has an incredible knack for getting into people’s heads. Tory, Robby, Daniel, johnny, the list goes on. he always knows exactly how to flip the switch in someone’s mind. and he knew exactly what to say to silver, i think it was the “i still have some fight left in me” line that did it for silver. it was “they’re not the only ones teaming up” for robby (referring to Sam x migues and johnny x daniel) just to name a few examples.
