00:00Why did Tony tell Hulk to sleep in Avengers Age of Ultron?
00:04If we pay attention, when Tony trapped Hulk in the containment cage,
00:07we see that the cage sprayed some kind of gas inside before fully closing around Hulk.
00:11And throughout the entire fight, Tony kept spraying this gas directly into Hulk's face.
00:15Toward the end of the fight, we can see that Hulk starts having some hallucinations.
00:18The spray had already begun to take effect.
