Mark Trail: She's ALIVE!

Seriously, though, placing yourself in Sassy's position, you've got to ask yourself which is really more terrifying. In one scenario, you've got a very stupid, giant-headed, cold-blooded reptile beast that constantly looks as though it could devour you at any moment. And in the other, you've got an alligator.

To be sure, neither is a great option, but at least once you get away from the gator, you're done with it. Rusty, on the other hand, will mindlessly follow after you to the ends of the earth. The gator is also probably mortal, whereas Rusty is almost certainly some sort of zombie, seeing as he would be dead many times over by now if he could actually be killed.

All things considered, Sassy should take her chances with the gator. Even if she gets eaten, it will still be better than living in Lost Forest.
