Nebula Prime tries desperately to warn…

“Yeah, we’re just diving in, keep up!”
Nebula Prime tries desperately to warn Clint and Natasha but Thanos’ ship appears overhead and just scoops her up.
On Earth 2012, Scott is freaking out because they’ve lost the Tesseract and only have enough Pym particles for one more journey each. But Steve and Tony remember that Camp Lehigh (where Cap spent many an idyllic summer day knocking down flagpoles and throwing himself on grenades) held both the Tesseract and all the Pym particles they can eat. They send Scott back home with the sceptre and Steve and Tony head to their most dangerous and terrifying destination yet.

Hyuck hyuck hyuck.
While Steve goes looking to score some Pym Particle (also known by its street names: P-Dust, Shrink-a-Dink, Tom Cruise…) Tony goes looking for the Tesseract. Fortunately, the seventies were a simpler, more trusting time where people left their doors unlocked and their children near BBC presenters and the Tesseract is just stashed in a big iron box without even an alarm or anything. I’ve known packed lunches with better security. Tony runs into his father Howard and the two men talk about parenthood.
Meanwhile, Steve distracts a young Hank Pym who the movie helpfully shows was already awful in the seventies. Steve grabs a couple of test tubes of quality Smoll (as it’s sometimes called on the mean streets of the quantum realm) but has to duck into another office to avoid base security. There, he sees Peggy Carter, the lady that he abandoned for a common iceberg, the cad.
