Markus gives a severe look to the woman in front of him. "Oh, these pants? You see, we are collectors of old vault technology. Since you seem to know so much about vaults, you don't happen to know any vaults in the area, do you? Or perhaps people who trades or collects this stuff like ourselves? As you can see we already have vault suits, those are of no interest ot us, we are interested in tech, more specifically computer parts specific to vaults, perhaps water purification systems." His tone showed slight irony, like saying "I don't give a damn if you believe me or not". Markus was not about to give away the location of the vault to anyone, specially with those mutants running around.
