Isaac and his mother... Naaaah, I'm not gonna bore you with the beginning of The Binding of Isaac. Instead I'll give you the gist of it. Mother is extremely religious, a disembodied voice tells her that Isaac is corrupted by sin, she slowly takes everything away, the disembodied voice tells her to kill Isaac to prove her utmost devotion to "God" (highly doubt the voice is really God, but if it is, fuck him then.) Now, what if this video game was actually real? The RWBYverse is the root of his existence I guess.
