Zed: What is done cannot be undone

Okay so I know all the lore updates are coming but I haven't seen them sooooooo

THEORY TIME also I made a post about Zed before but right now: Zed might've been willing to talk with his master but the box of shadows tricked him "heard Zed cry out in pain" to think he was being attacked to protect itself, and when Zed focused his mind had twisted his reality to 'they invite us in then strike out at us while trying to get me to destroy my source of strength?!'

Just a theory because we don't know what the shadow box is capable of... But he'll always be salty with Shen, but that's how rivals are... Anywho tell me what you think below.
