Ever since the incident with the baby and her mother on the floor above, she had been allowed more freedom. The Winter Soldier - Peggy, apparently - had memories bleeding and blending in her head. She remembered killing Stark's parents, she remembered the cries of her own daughter; two lives merging into one head and only half felt like real memories. During the day, she tinkered with her own mechanical arm just for something to do.
She had no more visitors than her family, though she didn't blame them for wanting to keep their distance either. The knock, when it came, was a surprise. She hoped it wasn't more tests.
