[Babysitting adventures!]
[What happens when all of Bonnie's regular babysitters are unavailable? It's Uncle Bruce's turn to take one for the team, of course. That's why the little girl is sitting at his lab completely still. Not bothering him at all. Just staring at him.
Staring and staring.
And staring.
Before she left on a mission, Autie Nat very clearly asked her to keep an eye on him, which she will do because the kid is starstruck with the Black Widow. Not as much as she is with the Winter Soldier, but enough to want to make her proud.]
