The Watcher: I am the Watcher. I am your guide through these vast new realities. Follow me, and dare to face the unknown, and ponder the question: what if?
The Watcher: I am the Watcher. I observe all that transpires here. And I do not, can not, will not interfere.
The Watcher: Journey to face the unknown, and ponder the question: what if?
The Watcher: Space, time, reality. It's more than a linear path. It's a prism of endless possibility.
What If... Ultron Won? - S1-E8
Plot hole: At the end of the previous episode, the Watcher gets surprised (literally saying "wait, what?") by the arrival of Infinity Ultron inside Party Thor's universe.In this episode we find out the story of Ultron.Ultron realises for the first time that there are other universes to conquer right then because he can'hear' the Watcher talk (to whom?) and goes after him.So the two episodes don't match;Ultron couldn't have reached the other universe "before" his realization, and Uatu is again surprised by it.
