X-Men: Days of Future Past2014

[Charles Xavier is exasperated over failing to work Cerebro again after so many years]

Hank McCoy:
I'll go check the generator.

Wolverine:
It's not the machinery, is it!

Charles:
I can't do this!

Logan:
Yes, you can!

Charles:
No, I can't!

Wolverine:
You're just a little rusty.

Charles:
You don't understand, it's not a question of being "rusty!" I can flip the switches, I can turn the knobs, but my power doesn't come from here [points to his head], it comes from...here [points to his heart]. And it's broken. I feel like one of my students. Helpless. It was a mistake coming down here , it was a mistake freeing Eric, this whole thing has been one bloody mistake! I'm sorry, Logan, but they sent back the wrong man! [Xavier starts to leave]

Wolverine:
You're right! [Xavier stops, surprised to hear him admit this] Actually, it was supposed to be you. But I was the only one who could physically make the trip. And, uh, I don't even know how long I've got here. But I do know that a long time ago-well, actually, a long time from now-I was your most helpless student. And you unlocked my mind. You showed me what I was, you showed me what I could be. I don't know how to do that for you, you're right, I don't! But I think I know someone who might. Look...into my mind.

Charles Xavier:
You saw what I just did to Cerebro! You don't want me inside your head!

Wolverine:
[amused] There's no damage you can do that hasn't already been done, trust me!

Charles:
 :[reads Logan's mind and see his torture at the hands of Weapon X, his fragmented memories, the death of Jean Grey, and his hard life.] You poor, poor man.

Wolverine:
Look past me.

Charles:
No, I don't want your suffering, I don't want your future!

Wolverine:
Look past my future! Look for your future. That's it. That's it.

[Charles reads Logan's mind and appears in the future, where Professor X awaits him.]

Professor X:
Charles.

Charles:
Charles. [looks around to see the dire situation that both mutants and humanity face with the Sentinels in 2023.] Is this what becomes of us? Erik was right. Humanity does this to us.

Professor X:
Not if we show them a better path.

Charles:
You still believe?

Professor X:
Just because someone stumbles and loses their way, it doesn't mean they're lost forever. Sometimes, we all need a little help.

Charles:
I'm not the man I was. I open my mind up and it almost overwhelms me.

Professor X:
You're afraid. I remember. And Cerebro knows it.

Charles:
All those voices…so much…pain.

Professor X:
It's not their pain you're afraid of. It's yours, Charles. And as frightening as it may be, that pain will make you stronger. If you allow yourself to feel it, embrace it, it will make you more powerful than you ever imagined. It's the greatest gift we have: to bear their pain without breaking. And it comes from the most human part of us: hope. [shows Charles his school for Mutants, his own compassion, what he fights for which helps ease his past self's mind.] Please, Charles, we need you to hope again. [Xavier, stunned, breaks the psychic link]

Wolverine:
Find what you were looking for?

[The lights return. Hank enters, having fixed the generator.]

Hank McCoy:
The power's back on.

Charles:
Yes. Yes, it is.

[Wolverine smiles.]:
