Emma had left the armory without a weapon, she was better that that. Well that's what she told herself, she actually got distracted by her own thoughts and left. In fact she was still thinking when she stepped in a puddle of metallic goo. Her first thought was that it was mercury her second was to wipe it on a near by corpse. Except she didn't because she realized that she just thought of wiping whatever was on her foot on a dead body. That was one of many things that society generally frowned upon. So she didn't, instead she stepped over the dead body and continued walking, lost once again in thought and now with a metallic trail because she never ended up wiping the goo off.
