What does Marty see in Leo?

“A lie told often enough becomes truth”

-Vladimir Lenin

"I got attention by being funny at school, pretending to be retarded, and jumping around with a deformed hand. "

-Leonardo DiCaprio

Damned if I know.
What I do know is this:
-there were multiple assassination attempts on Lenin's life
-history has proven itself to be cyclical

Take from that what you will.
