The airhorn exploded, letting out the most horrifying noise that Steve could ever remember hearing. Ever. Well…except for maybe…but there was no time to finish that thought. Nor was their time to be scared. Steve managed to squeeze it in, nevertheless.
"Run!" Thor roared.
Everyone without a weapon (that is, everyone except Thor and Steve) obeyed without a second thought. Normally this wouldn't have been the case, but it was three o'clock in the morning, and it had been a generous offer Thor had made.
The Hulk attacked Steve, and he blocked the blow with his shield which had been previously hidden surreptitiously underneath his bathrobe.
"Have no fear, Captain!" Thor cried, raising Mjolnir and packing Hulk a mighty blow, which sent him flying to the other side of the corridor.
It was at that instant that the unthinkable, the utterly impossible happened.
Thor fell asleep.
With his mighty hammer on his stomach.
Steve ran through his options. The Hulk was storming towards the sleeping individual on the floor. Really, there was only one moral option. He had to save Thor from being smashed. He threw himself at Thor and tried to move him, even though the hammer had him pinned to the ground. As he pulled at Thor's leg, there was a metallic whoosh, and Mjolnir fell off of Thor. Steve gasped. Could it be?
Captain America lunged for Mjolnir, picking it up and hitting the furious Hulk in the stomach.
This all happened in barely a second.
Thus followed an epic battle between the worthy Captain, and the probably not-so-worthy Hulk, with Thor out for the count, dreaming about his brother, as per usual.
Meanwhile, Natasha, Clint, and Tony where running towards the weapon vault, looking for tranquilizer dart guns. Or tasers. Anything that could put the Hulk out of commission long enough for him to turn back to Bruce Banner.
"Is a tranquilizer dart gun gonna work?" Clint asked, unsure.
Natasha loaded her gun, looking calm as always. "I hope so."
Then a figure stepped out of the shadows.
"Ah, so we meet again," said Loki.
