Why does Armen say "sorry do I now you"?

if you have seen the trailer go and see it. so we all now that Armen at the end says "do I now you" now there are meany posable ways for this to happen to poor Armen so lets brain storm some off are heads shall we.

1. Armen having Amnesia: Drake mines the sacred diamond and it kills Armen or so we thought. Armen could have servived and he was left there and Drake didnt now that Armen was not dead so the mountins magic might have lefted him with no memorys and helped armen get strangth to walk out before it eruped so after he did he was given magic and some mana and when to find a place to call home. (well notch bless him).

2. Herobrine: Herobrine left armen mermeryless and left him to die but armen is found inthe mounted by a persons a mage who could take care of him giving armen magic to live off of.
