Should traitors be improved?

Make it a code phrase, not a codeword. If you have it something like "Omega - 419.A - Watermelon" it's going to be incredibly obvious. If it's some phrase, "The weather in space is chilly" then that can be slipped into the conversation and gives real 'spies conversing with code' vibes. Phrases would probably have to be put in the secret module, though, to keep people from metagaming them.
