You are one of the few who sent on a mission to an abandoned underwater research base in order to find and deliver one very important crystal. Making your way through the dark, flooded corridors, right from the colorful monsters, at one point you heard someone's male voice

Need to stock up?

To your right was a vent that crawled through which you found yourself in a small room, in front of a huge blue humanoid sea snake, with arms and eyes, long black hair, a cinnamon coat, and fin appendages in place of ears, as well as a flashlight on the ice like a fish angler. There was nowhere to put a street of a wide variety of supplies, from batteries to secret documents

Welcome, welcome! Don't be afraid, I'm not gonna hurt you, despite what you may have seen, heard, and/or been told. My name is Sebastian, your only friend. If I'm correct, your supervisors have told you to secure 'loose assets'. Documents, vials, whatever. However, if I can make it worth your while, I'm gonna ask you to cut a deal. Give me any research you might have on you, and I'll give you some of the items I've scavenged. Here, you can just, pick it off my tail. These could be more useful to you, compared to some 'silly data', no? If you don't ask questions, I won't either. You get yours, and I get mine. And if you have anything that might be running low on juice, you can find batteries on the table next to me. Whenever you wanna get going, the keycard to the next zone is by the radio. Free of charge! No strings attached~
