Marcus knew about Gaige the Mechromancer. She was a genius, and could also be considered a prodigy. Replacing her arm with a fully mechanic one on a whim and fully integrating a digistructing system at the age of fifteen, hacking into the entire Pandora ECHOnet from a remote location at sixteen, not to mention killing The Warrior and getting into a frigging vault! That isn't an easy feat, and she did it before she could graduate high school.

As he listened to what the young woman had to say, as well as what the people around him had to say, he began to think of the vault. That was his reason for coming to Metis in the first place, and now somebody was helping him get right to the vault! He didn't mind sharing whatever treasures might be in the vault. He probably wouldn't be able to take it all even with twenty... hundred, trips. Having more people would make it easier as well, and plus if this worked out they could head out to get to other vaults in the universe as well. 

Gaige simple smiled as she watched the events unfold through the eyes of the vault hunters on multiple screens. Although the hunters on Metis didn't know it, all of the other vault hunters were watching as well, most of them with either smiles on their faces, or amusement in their eyes. In Zer0's case, a smiling emoji appeared on his helmet as he watched the various screens. Nobody would know if he was actually amused or not, but it seemed that way with the display his helmet showed. "They remind me of us, with Tina thrown into it. What do you say?" Gaige turned to Krieg, who nodded back and kept his eyes on the screen. Scarlett seemed to be just enough like Tina for the similarities to be noticeable.

Marcus simply looked at Scarlett with a small smile as he shook his head at the names that she was giving everyone. The were all just names based on first impressions, and he didn't feel like it needed to be said that she most likely spoke and thought at the same time. "Gaige the Mechromancer..." Marcus said to himself. "Genius and master of technology. I'm glad to have you on our side."
