Just as opposed to it always being Reed doing something Tony considers reckless.

Head in clouds, double and triple checking his method and findings. Sue thought she wanted Reed to be, well more like Doom, decisive. And she does get that, when the situation is clearer, than her set up where she's said she was leaving and Reed let her walk just wanting her happy.

I did find in the commentary and interviews it weird how much they went on about her mom qualities and how maternal the actress was.
