SCP-738-4: Well, look who it is! How the hell have you been? What can I do for you?
SCP-001-03: Just a message delivery, Jack. Next time you head back, tell everyone to get ready. The contract is winding down.
SCP-738-4: Are you shitting me? Not pulling some sort of trickery-fuckery?
SCP-001-03: Not at all.
SCP-738-4: Really time for the scrap, eh? Bloody asshole fuck it’s been long enough. Y’know what? For you, no charge. It’s on me this time. Right out of the kindness of my shriveled black heart.
SCP-001-03: Well, maybe not so black.
SCP-738-4: [Laughs, slaps table] You’re killing me here! See, that’s why I like you: always got a joke and a smile.
