They'd made the cross-town journey in a waiting car, and a good thing too. Bucky was trying to keep a low-profile - being spotted carrying Tony Stark's corpse through an alley wouldn't do much good for anonymity, and even a ghost could only be so unobserved with a companion and a body over their shoulder. Stealing a car was the other option, though that, too, would have brought undue attention.
Pulling Pepper's car up to the door gave him the latitude to carry Tony's body up the stairs with an arm around his shoulder like a drunken friend. Only someone paying close attention would have noticed that his feet were dragging on the ground. The door was open, so he went through quickly, his free hand at his side, just in case. He went ahead in first, trusting Pepper to watch behind him - because she was invested in Stark. Not because he trusted anyone implicitly, under any circumstances.
The two women sitting on the couch were a strange sight. The dark house bore all the signs of an entire family, but here were two silent people, sitting without touching anything, waiting for a corpse to arrive. He remembered what Clem had said, about everyone she knew leaving.
He had not thought, yet, about Steve.
This place felt uninhabited. He made his usual unconscious sweep of the surroundings, almost unnoticeable. There was a sucker lying on the floor under the couch, just behind Clem's feet.
He didn't recognize the other woman, but she must be the doctor who was mentioned. He fixed her with a steady gaze. She seemed harmless enough, but obviously that didn't mean anything at all.
While Clem might not know it, she now had a favor in her pocket, one that she could deploy at any time. The same went for her friend the doctor, if she kept quiet. His hair and clothes, bruised but intact body armor, were still wet from the Bay, and the metal arm at his side gleamed, wet and vaguely sinister.
