Let's have an I.Q. test, shall we?
- Go back to the riverbank to await help?
- Go back to the riverbank and call 911 again to update them
- Go back to the riverbank and polish your cane
- Attempt to remove the driver - who is suspended upside down - from the SUV and take her back to shore
Yes, answers 1 through 3 are viable options. Option 4 is what Lucie does, resulting, you guessed it, physical injury, a lost cane and a very suspicious scene for the police to happen upon. And when someone asks Lucie WHY she engaged in such epic stupidity she tells them "I couldn't just leave her hanging there."
Oh yes, you can, Lucie. Especially since you had no reasonable chance of getting her back to shore, you numb skull.
