Maybe Charles could do something with time but then again maybe they meet a Mutant like Shadowcast (who sent Logan back in Days of Future Past) can help them hop through time. It could be interesting to let Laura and Logan enjoy the past without so much danger.

Everyone will have all the banter. I still can't wait to see Logan's face when Laura does speak. I wonder if she'll enjoy Tony as a father figure or Logan. Knowing Tony he'd try to mentor Laura just to piss off Logan.
