SAM privately informs Ryder that, by the way, he's not just an AI! He's also an AI that can literally reach into your body and control you. Your dad didn't want anyone to know, but SAM can actually make you faster, stronger, a better biotic, etc.

There's some other stuff that SAM can't remember, probably because Dad locked away those memories. Cool, thanks Dad. Let's go scavenge his stuff!
