So at the end of What If Thor was an only child, Watcher was surprised to see Ultron attack the Thor universe. And in What if Ultron won, we learn about the Watcher who made ultron aware of the multiverse.
my question is why watcher is surprised to see ultron in episode 7 if he fights ultron who is trying to destroy the multiverse, and if he hasn't met Ultron yet, why does ultron find out about the multiverse in episode 7 ?
I assume The Watcher investigates the universe where Ultron came from and the time before he attacked the Multiverse. Instead of figuring out its origins, he messes up and makes Ultron aware of the Multiverse.
but if that's not the reason, I don't understand at all
