You would have thought that, when the unstoppable alien menace invaded in Avengers Assemble, Fury might have thought to give her a bell, because there was no way to see that the Avengers would win.
Or when Shield turned out to be taken over by Hydra and the Helicarriers were going to kill millions.
Or when Ultron started tearing shit up.
Or when Thanos forces first turned up, killed thousands, kidnapped the wizard, Iron Man and Spiderman disappeared, Thor and the Hulk were missing, and Captain America, Black Widow and Falcon were disavowed and in the wind, Ant Man and Hawkeye were under house arrest.
Or even after the events of Civil war when the Avengers initiative turned to shit.
JUST SAYING.
