During 'The Amulet' quest the player chooses to kill Grim (rewards 60 EXP) or spare him (he can then be used as backup/ally to help in the fight).
Grim: And here we are. Far out, where Diego can't hear you.
Grim: Bloodwyn sends his regards.
You: How do I get accepted into the camp?
Grim: I take it you ain't interested in digging. In that case your best bet is to join the Shadows. As far as I know, you'll need someone to vouch for you. Someone to show you the ropes.
Grim: You should stick with Diego - I did, too. He's all right.
Grim: Later on, your mentor is gonna give you a test of his own - but only AFTER you've scored some points with the other Shadows.
Grim: Once you've passed that, they'll let you see Gomez. Then it's up to him.
Grim: Hey, you! You must be the freshie who's been trying to get into our camp.
You: And if I am?
Grim: Well. I could help you ...
You: How?
Grim: I saw a guy right outside the camp, bragging about how he's stolen some sort of amulet from the ore barons. Nicked it right off the last convoy.
Grim: He probably still has it on him. If we take him and his pal on together, we might just make it - I can't do it by myself. What do you say?
You: I'm in.
Grim: Great! Tell me when you're ready.
You: Not interested. Go find someone else.
Grim: Really? You're not gonna make it far like this. Let me know if you change your mind.
You: Ahh, forget about it. We go halves, or you can beat up that guy alone.
Grim: All right, all right, halves it is. Guess it'll be enough for the two of us. So - you're in?
You: What do we do with that amulet?
Grim: What do you think? I'll take it back to the barons and get myself a nice word. But don't worry, I'll tell them you gave me a hand. That'll earn you some points with Gomez.
You: Hey. I'm new here.
Grim: Fresh in, are you? I'm Grim - only just got here myself. I came in with the haul last week.
You: How's your progress with the Shadows?
Grim: So far, I convinced Dexter, Sly, and Fingers. They're pretty important.
Grim: Oh, man! Did you know In Extremo is here?
You: What's it like living here?
Grim: It's fine. So long as you pay the warders ...
You: Asshole.
Grim: Oh, come on - we're both playing the same game, aren't we? I don't wanna work in those mines either.
Grim: That's why I'll just do what the warders tell me. It's the only way they'll ever take me in.
Grim: Take your best guess. Never cross a warder, man - that's the first and most important lesson everyone learns in here.
Grim: It's nothing personal. So - are we good? Or do you want me to beat you up again?
You: Let's the bury the hatchet.
Grim: Never was one as far as I'm concerned. Glad you could take my perspective. I'm on your side from now on.
Grim: If you ever need someone to give you backup, let me know. I owe you one.
You: Shut up and fight.
Grim: Oh, come on, man ...
You: Let's go get that amulet.
Grim: Music to my ears.
You: What was YOUR test?
Grim: I can't tell you that, man. It's confidential.
