UN-BELIEVABLE. AND ABSOLUTELY MIND BLOWING. This episode completely redeems the potential of Avengers - Age of Ultron, in ways you couldn't even have dreamt of. With Nat and Clint being the last survivors of 'The Age of Ultron', they are the only ones with the will to make things right again. 

When Kevin Feige said they would be flipping the script with What If...?, we never expected it to be to such an extent. This will make you question everything you ever witnessed with Marvel's movies or T.V shows. Also stary tuned till the end, as there is a big reveal towards the ending of this episode.
