It was not caused by the Russians, as far as I know. I don't think any of them have access to kill abilities, other than the desperado one. Also, we only knew he was a Chinese spy after his death, because RUSSIAN_SPY#3 was told by the Russian double agent, and then RUSSIAN_SPY#3 posted it.

There is a lot of Facebook chatting and forum posting now. Basically, Jingyi tricked Justine, ajliu's body double, into taking the potato, which causes the Russians to lose if a Russian spy is in possession of it at game end. So now ajliu needs to get rid of it.

Also, ksedlar and jessk were arguing about whether or not the Russian double agent should reveal who the Chinese are. Ksedlar really thinks they should, and jessk thinks they shouldn't.
