HOW LONG TO GO, DO YOU THINK?

30, 40 YARDS, I DON'T KNOW…

BUT, FOR THE LAST TIME, BE QUIET!

WE'LL NEVER MAKE IT…

LIKE RATS…

STEVE, I'M SUFFOCATING! I WANT TO GET OUT! HELP!

HE…

WE'LL GET THERE, SON, I PROMISE.

I NEED TO GET THERE!

THIS WATER… IT'S NOT POSSIBLE… UNLESS..

UNLESS THE PIPE IS BLOCKED!

THE WATER…

TURN ON YOUR BACK, BILLY.

AND, ABOVE ALL, DON'T PANIC!
