It starts with Junior Jupiter, Peggy supposes. Dum Dum slips Junior's dogtags into Peggy hands as they part. He doesn't say why; Dum Dum never really explains himself often.

She figures she's entrusted with Junior's tags to make sure they get home. She searches for weeks, in between trying to prove Howard's innocence and trying not to get killed. She doesn't find his family.

She keeps the dogtags in her desk at the SSR. Occasionally, when no one is looking, she'll open the drawer and stare at them.

Every now and again, a new set of dogtags will appear to Peggy through various means: Dum Dum himself, from Mr Jarvis, or through the mail. Peggy never questions it. She makes the effort to find the family each time before tucking them away in her drawer.

Until the last one comes in. It's Dum Dum's tags. She knows he doesn't have any family so she grips them in her hand and hold them tightly for a long moment.

She's long since traded SSR for SHIELD. She opens the drawer the holds the other dogtags. There's eight of them total; two more and she'd have the set.

Peggy takes the time to hang each of them in her office. People believe that the photo of her shaking JFK's hand that sits on her desk is her most prized possession, but they're wrong. It's the eight dogtags that hang on her wall.

Because those eight tags represent eight lives that believed she was their family at the very end. And she was.
