???he knew the flower was poison??? Arent you suspicious, why would you show your plans???

Who knew the flower was poisonous? Is it the guard or the silver haired dude?

If you're talking about the silver haired dude I think he realize it the flower was poisoned when his hand goes numb. Idk what's the deal with the guard tho.

But silver hair dude didn't even touch the flower, he barely approached it before backtracking
