Just watched it, and thought once again Thanos punked out, as no way he gets split in half if he has the IG!

Ultron IG seemed to be able to fully function and work across the multiverse, and the Watcher was shown much more powerful then remember him ever being here...
Liked how his last resort was to seek out the Dr Strange form the prior what if and seeh his aid to stopping Ultron!

part one, next week next part!
