corey found the tapes in his garage. he probably stumbled across them & had forgotten he had them or thought he lost them. i kinda understand this because when you go through a traumatic experience, your mind tends to compartmentalize it (mk ultra, anyone?) and your mind works hard at forgetting details because the associations are painful. ESPECIALLY, if you feel like your story was not being heard or appropriately addressed. ultimately, i think this is good for general red pilling.
