So let's say that when Kyle Reece comes to Los Angeles, he encounters not just waitress Sarah Conner but David Banner who is a dishwasher/helper at the restaurant. David's been helping Sarah with some of her college homework.
The crazy stuff starts happening, and at some juncture (say, the police station, "I'll be back"), David Hulks out, to the horror of Kyle and Sarah, but the big guy seems to help against the Terminator.

So how does this end? does the Hulk get Terminated, or does the T-800 get shredded by gamma hands?
