I'm sure i've heard those lines somewhere, but I can't for the life of me tell you where. I'm sure I just heard them, and they were subconsciously etched into my mind, I'm sorry
I have referenced Gordon as The One Free Man a few times throughout my story, but I'll try and see if I can't fit in an "Opener of the Way" reference in there too
The only title I've heard Shepard called, atleast in the games so far is: The Savior of the Citadel.
