My itty-bitty attempt at humor...If anyone wants to know what the hell Loki is doing here, may I suggest reading my other fic, "Moments on the Rooftop"? If you just accept the Silvertongue's presence, though, that's totally fine, too.
Enjoy!
(These are Marvel's characters.)
Clint stares. It's all he can do, really. Natasha is there, too, an unreadable look on her face, but she stares all the same. Bruce's expression looks like Natasha's; Thor is staring, but it's in confusion, Tony and Loki are both staring with gleaming eyes, and Steve is staring, too.
So really, everyone is staring at Captain America's shield.
But it's Steve's stare that has a frustrated and angry feel that Clint can't help likening to a bull about to charge. Hey, he calls 'em like he sees 'em. In hindsight, he probably should have told Steve to calm down, or told Loki and Tony to leave the room...or, well, the state.
But there's only so much you can do through the haze of shock of seeing Captain America's shield, the symbol of national heroism, proudly displaying the colors of the German flag.
Tony, of course, breaks the silence by stage whispering to Loki, "I thought you were going to make it the Hydra symbol."
And Steve just charges.
Clint is impressed with Tony's ability to dodge out of the way, and then loses the feeling when Tony, instead of moving to the right, moves to the left and ends up doubled over the back of a sofa. Loki just teleports away to stand behind Thor.
Steve grabs the back of Tony's shirt, turns him over, and holds him up by his collar. The inventor is mumbling something about the cost of the shirt when Steve says in a scary, quiet voice that makes everyone shudder, "Put. On. The. Suit."
Clint can see Tony calculating the chances of getting out of this one, and although the archer himself is no expert on math, even he knows those chances are slim.
Tony nods an agreement and practically scurries to his workshop while Steve stalks across the room to go wait for Tony in the training room. Clint causally says, "What about Loki?" and doesn't miss the way the trickster's gaze latches onto him in the form of a glare from over Thor's shoulder.
Steve turns and is about to say something when Loki says, "I am the only one who can change the shield back, Captain. Hurt me, and your shield will forever stay the flag of Germany."
Steve glares and Loki smiles. The blond seems to deflate and says gruffly, "I'll deal with you later."
"You don't have to," the trickster says kindly (but not really; Clint can see the utter mirth in his eyes) and Steve turns to see his shield back to normal. He looks suspiciously to Loki and continues stalking away to the training room, where Tony is no doubt nervously waiting for him.
If Tony looks a bit more bruised than he did yesterday, no one says anything. But Clint can't help going, "Is this a bruise? How about this one?" and pressing on the purple spots on Tony's arm.
It doesn't help matters at all when Clint, one floor above the rest of the team, hears a shout of "Stark!" and a scream of "I swear to God, Steve, I didn't do it," and goes down stairs to be greeted with a very Canadian shield.
Hah! Aren't I soooo hilarious?
