The LW said she doesn't have the usual clues. It's a lot easier finding my husband in a store now, because he uses a cane now. Before, I'd find someone with his build, and look to see if I recognized his shirt.

The LW's problem is, they all are homogenous. Same suits, same build, same race, etc. It's harder to pick out the differences. She needs to sit with two in a room sometime, and while they talk to each other, look for things like a mole that one has and not the other. Eventually, she'd figure out the bosses, if not the lower level people.
