I feel like it’s obvious but I’m feeling like Fury is going to die and we’ll find out the real Fury remained in space and used one of those pod things to clone himself to a Skrull who took his place. He’s looking increasingly pained, like he stood by and watched someone die when he should have blown his cover to save them. Reckon it’s a Skrull plant and Fury is still in space working on whatever is so important he left Earth for, which his Skrull plant doesn’t know about, which is why he hasn’t said why he left when anyone asks him.
