I saved the first guard in Residue Processing by removing all threats to him. Now he just stands around, and will not speak to me, as if he has no lines.
Same here. I wondered if it’s normal, but it stuck out to me because every guard before has spoken or responded to me but he just stood there!
That’s probably due to the fact he’s supposed to be eaten by the barnacle down the hall, thus acquiring a new sidearm.
…unless you give that up in exchange for saving him… At the very least he should be a default barney.
