Secondhand Lions/WMG

If the real Jasmine were alive at the time the movie took place...
She would do a lot worse to Stan than what the lion did. Think about it: Back in her day she tried to outrace her future husband (Hub). She tried to kill herself rather than be the newest addition to the Shiek's Harem. To top it off she was able to hold her own against assassins trained to kill Hub.

If she were alive at the time she would warm up to Walter much like Hub and Garth. To take it further also develop maternal instinct for the boy. If Stan ever harmed Walter like he did in front of her she would probably slice his face with the same dagger she planned to kill herself with.
