(Oh and spaces work, so Endo, you were wrong).
(Apparition of) Konrad: "It seems reports of my... survival... have been greatly exaggerated"
Walker: "This isn't possible"
Konrad: "Oh I assure you, it is"
Konrad: "Not how why. You were never meant to come here:
(Flashback Walker: "We have our orders, leave the city and radio command from outside the storm wall, they send in the cavalry, we go home"
Walker: What happened here was out of my control...
Konrad: "WAS IT? None of this would've happened if you just stopped. But on- you marched. And for what?"
Walker: "W-We tried to save you."
Konrad: "You're no savior, your talents lie elsewhere."
(Flashback Lugo: "THIS IS YOUR FAULT GODDAMMIT!"
Flashback Adams: "STOP RIGHT THERE LUGO!"
FB Lugo: "HE WOULDN'T LISTEN!"
FB Adams: "We didn't have a choice!"
FB Lugo: "HE TURNED US INTO FUCKING KILLERS!"
Walker: "This isn't my fault!"
Konrad: "It takes a strong man to deny what's in front of him and if the truth is undeniable, you create your own"
(Flashback Adams: "What happened?"
Flashback Lugo: "I dunno he just stopped moving!"
FB Adams: "Walker! Snap of it!"
FB Walker: "I get it... we have to choose")
Konrad: "The truth Walker is that you came here to be something you're not, a hero."
(Flashback Walker: "LUGO?"
Flashback (Heavy) Lugo: "YOU LEFT ME TO DIE!")
Konrad: "I'm here because you can accept what you've done. It broke you."
(Flashback Walker [To a broken radio]: "Colonel? Colonel please...")
Konrad: "I know the truth is hard to hear Walker, but it's time, you're all that's left, and we can't live this lie forever...
I'm going to count to five, then I'm pulling the trigger."
Walker: "Y-You're not real... this is all in my head."
Konrad: "Are you sure? Maybe it's in mine! ONE"
Walker: "No... all this, it was YOUR fault!"
Konrad: "If that's what you believe then shoot me! TWO"
Walker: "I-I didn't mean to hurt anybody..."
Konrad: "No one ever does Walker... THREE...
Is this really what you want Walker?"
