i think watermark explained somewhere up above.
Watermark was pondering killing christie for the reverse psychology dynamic, (i.e. "why would i kill the very person trying to lynch me? that's way to obvious, i would never do that") but watermark thought it was to risky, (as presumably you are having to rely on interpretations that you can't necessarily predict), so then watermark decided you would be the safer bet. But then usfreedom kill christie anyway.
