Miscellaneous Movie Musings the Sequel

[Alex]

Would you be willing to expand more on Salt not caring about her husband?

Spoiler:

Since how much she cared for him was the driving force behind what she did through the whole movie in not killing the Russian president, killing all the other spies, and then preventing the missiles from being launched.

She didn't react visibly when he was killed, but that was because she couldn't since killing him in front of her was a test of her loyalty.
