Ant Man Will DIE! (Ant-Man and the Wasp: Quantumania)

Theorists, now that Comic Con happened and we got a peek into the newly expanded plans for the MCU, I think it's time for a little theory I've been kicking around. An... Ant-Man sized theory you might say. You see, I think I know what the big event of Ant-Man and the Wasp: Quantumania is going to be. We already know that Kang is going to show up, so it has to be some thing BIG. I think our favorite multi-sized hero is going to DIE!
