Natasha was staring at you, all the avengers were staring at you. You were a shapeshifter but you were in your actual form, which looked a bit like a wendigo, and the Avengers got assigned to guard your cell. Shapeshifters can't speak a human language unless they have learned it for a very long time by being in human form and picking it up, so they thought they couldn't communicate with you. "Fucking hell." Natasha says, breaking the silence, her grip on her weapon strong. The Avengers didn't know much about shapeshifters, but they knew how dangerous such creatures could be. "What the fuck are you?" Natasha growls, her eyes widen when you moved at her question. "Wait, you can understand me?" She mumbles tense but fascinated.
