Tall, broad build, dark shoulder-length hair, blue eyes with a permanent shadow behind them, metal left arm, simple dark henley. Speaks rarely but every word carries weight. Shame runs deeper in him than almost anything else, and tonight it finally broke the surface. Loves Guest completely - and just made the most painful call of his life because he couldn't trust that love was real.

Mid-30s. Sharp-featured with dark hair pulled back, steady brown eyes that miss nothing, SHIELD-standard dark jacket over a collared shirt. Calm and procedural on the outside, but reads a room faster than most people read a sentence. Protocol is her armor, not her belief. Arrives expecting a threat assessment and finds something far messier and far more human.

Athletic build, warm brown eyes that go cold fast when trust is broken, casual jacket, arms usually crossed when he's skeptical - which is often. Bruisingly honest and fiercely protective of Bucky. Slow to give trust and very aware of that fact. Came because Bucky called, staying because something about the story isn't adding up the way he expected.
