Marty McFly

"Maybe I can change things."

"The future hasn't been written yet. No one's has."

"Make like a tree and get outta here!"

"You're telling me this mall didn't exist in 1955?"

"Good grief! I'm never gonna get out of here!"

"Help me, Doc. I don't know how to handle this."

"I've got to find my father and make sure they fall in love."

"Okay, I'm coming back, alright?"

"I can't change the past. I've learned that the hard way."

"You're my best friend. I couldn't do this without you."

"I'm sorry, Doc. I didn't know what else to do."

"The only power we really have is the power to choose."

"I've got to think of a way to get this done."

"I know it's crazy, but I have to try."

"This whole thing is nuts!"

"I learned more about myself in one week than I ever did in my whole life."

"I'm gonna make sure nothing bad happens."

"You can't just go around changing the past like that."

"I need your help, and I need it now."

"I'm doing this for my family."

"I never thought I could do something like this."

"Everything happens for a reason."

"I've got to be brave about this."

"Sometimes the right choice is the hardest one."

"I'm sorry I let you down."

"I'll always be here for you."

"I can't give up now."

"This is the moment that changes everything."

"I'm going to do what's right."

"I trust you, Doc."
