10 MCU Loose Ends That Drive Fans Crazy

10. What Happened To The Stolen Pym Particles?

One of the MCU's most notorious loose ends revolves around a seemingly major plot development in the first Ant-Man movie that was strangely ignored.

Towards the end of that 2015 MCU entry, dick-bag HYDRA agent Mitch Carson runs off with a vial of precious Pym Particles, implying that he - and the rest of his shady organisation - will go on to use that technology for untold nefarious deeds.

Well, almost seven years later, those nefarious deeds have yet to materialise, and Carson himself has been completely MIA. In the wrong hands - and HYDRA is very much "the wrong hands" - Pym Particles could have devastating effects, so it feels like this should be a pretty major problem for the Avengers to take care of.

Well, apparently not!

Interestingly, a deleted scene from Ant-Man would've seen Paul Rudd's titular hero confronting Carson and swiping back the stolen goods, but this was removed with the sole intent of leaving the particles out there. So there has to be a plan, right? Will Ant-Man 3 provide some answers? We sure hope so.
