I love it when people try to counter this with "Well he's rampant so you can't believe him!"
Spark LITERALLY NEVER lies to you or gives you misinformation or even uses hyperbole (barring lies of omission).
He's not just gonna start making things up because he's crashing out.
Forerunnr vs. Human debate is trying to die down so I’m gonna just give the objective facts of the connection
Halo CE: Forerunners implied to be human, but left ambiguous
Halo 2: was going to reveal Forerunners as human for Arbiter’s character arc, but got scrapped (1/4)
