:52:01
What did you say?
- A bolt of lightning.
:52:04
Unfortunately, you never know
when or where it's ever going to strike.
:52:09
We do now.
:52:15
This is it!
:52:17
This is the answer.
:52:19
It says here that a bolt of lightning...
:52:22
...is going to strike the clock tower
at 10:04 p.m. next Saturday night!
:52:29
If we could somehow harness
this lightning...
:52:34
...channel it into the flux capacitor...
:52:38
...it just might work.
:52:40
Next Saturday night
we're sending you back to the future!
:52:45
All right. Saturday's good.
:52:47
I can spend a week in 1955.
l can hang out. You can show me around.
:52:51
That is out of the question.
You must not leave this house.
:52:54
You must not see or talk to anybody.
:52:56
Anything you do can have repercussions
on future events. Do you understand?
:53:01
Yeah. Sure. Okay.
:53:03
Marty...
:53:05
...have you interacted with anybody else
today besides me?
:53:10
Yeah, well, I might've sort of
bumped into my parents.
:53:13
Great Scott! Let me see that photograph
again of your brother.
:53:20
Just as I thought. This proves my theory.
Look at your brother.
:53:25
His head's gone. It's like it's been erased.
:53:29
Erased from existence.
:53:37
They really cleaned this place up.
Looks brand-new.
:53:39
According to my theory, you interfered
with your parents' first meeting.
:53:43
If they don't meet, they won't fall in love,
get married or have kids.
:53:46
That's why your brother's disappearing.
:53:48
Your sister will follow, and unless
you repair the damage, you're next.
:53:52
Sounds heavy.
- Weight has nothing to do with it.
:53:55
Which one's your pop?
:53:58
That's him.
:53:59
Okay. Okay, you guys.
