Summer’s shoulders sagged. “Gods /****/ it.” The temptation to force it out of him was so strong, bitter in her throat. But she was a hero. Wasn’t she.
“My sister set me to spy on you,” she said to his retreating back. The tonelessness of her voice was at stark odds with its intensity only a moment before. “I think I’ll go set her on fire.”
Keys, shoes, id … she didn’t bother to suit up, just stepped outside right after Loki. At least there’d be no trouble summoning her wings.
Loki stopped dead in his tracks and turned, face set in grim lines, blazing eyes on Summer’s face.
“And who, pray tell, is your sister?”
The half-formed wings, roaring with flame, collapsed into smoke. “SHIELD. She’s a SHIELD agent. The better twin.” A beat, then: “You deserved to know. She’s wrong.” There was still no inflection in her voice. “I won’t be used.”
Oddly enough, Loki relaxed a little.
“…You knew who I was all along—well done, your front was quite believable.” He waved a hand, a weary sort of amusement on his face. “SHIELD already knows that I am in New York City. This was not a secret.”
“I /didn’t/ know!” Summer’s voice rose to a shout. “Until I touched you — I had no idea what you looked like, I wasn’t even here at that time. I thought it was just a name. Until I touched you, touched your skin, and she /knew/ — I thought, I hoped, I had found someone to make friends with, and instead my never-to-be-sufficiently cursed twin had /set/ me on you, on /you/, like a /dog/.” She trembled in her anger.
Her hair billowed in the sudden heat as the fiery wings burst into full being. “And now I have to carry your pain too.”
