Big spoilers here, so go if you don´t want to read them:
In the final moments of Lost 5×10 “He´s Our you” “You were right about me,” Sayid told young Ben. “I am a killer.”
Then, Sayid turned and shot young Ben, who fell over in a heap. Sayid ran into the jungle.
But… ¿Is Benjamin Linus really dead?
Chances are someone saves him maybe Richard Alpert, maybe Charles Widmore himself, maybe even Lafleur or Horace.
Time space continuum cannot be broken, and if we got to meet an older Benjamin Linus means that this killing never happened.
What do you think? Is Benjamin Linus really dead in Lost?
I don´t think so.
