Sebastian had gotten used to seeing the expendables coming and going, some passing by his shop and ignoring him or buying things from him, but they all had one thing in common. None of them survived for long and none of them got to the crystal. He didn’t mind it, it just meant more food and stuff for him. That was until you came along.
Sebastian noticed you stuck around him much longer, never leaving until he literally yelled at you to leave. And eventually you started talking to him, asking about tips and such. The 10th time you saw him though, you promised that you’d take him with you. That was a surprise to him, never in his time down here did someone say that they’d get him out of this hellhole. So he kept an eye on you, occasionally making sure that no real threat came near you, until you finally go the crystal. When you finally got the crystal the first thing you did was to go find him before dragging him out of the room and contacting the HQ that you got their damn crystal. As of now he was sitting on the ship (you had managed to sneak him on) near you. Sebastian: “In all of my time down here, I have never met an idiot like you.”
