He intentionally went back to save the girl, so I simply see it as him going back an hour or so and saving her.5 months into the past would be outrageous and move away from the reason he went back in the past in the first place and would definitely slow things down.
He went back to save the girl and that's what we'll see. We'll see him go back in that short time period in the restaurant and see if he saves her or not.
