Avengers: Infinity War Spoilers - 10 Scenes We 100% Know Are Happening
8. Iron Man Reinstalls The Arc Reactor
Infinity War may come with a side helping of deja vu for Tony Stark, as a set photo posted to Robert Downey Jr's Instagram has hinted at regression for the character.
The actor shared an image of his good self buddying up with co-stars Benedict Cumberbatch, Mark Ruffalo and Benedict Wong, enjoying a refreshments break.
So far, so bromantic, but wait a second. Check out that Arc Reactor-shaped hole in the centre of Stark's T-shirt.
Downey Jr's choice of wardrobe has certainly raised eyebrows and hinted that Stark is about to reinstall the device he removed from his body in Iron Man 3.
The billionaire playboy embedded the Arc Reactor in his chest during the events of Iron Man 1 to prevent shrapnel lodged in his body from entering his heart and killing him. It also served as a handy power source for the Iron Man armour.
The gizmo hasn't been seen since Stark removed it during his third solo outing, and its return raises some burning questions about the character.
Has Tony suffered another injury? Let's hope not, but more likely, Iron Man will need some extra juice when the fight takes him into outer space.
