Attempting to lift them both would incur an attack of opportunity. Bull-rushing Shiro off of her would work- and you wouldn't incur an AoO because he can't see it coming. However... that's assuming you knew that there was someone overtop the Guard. Unless you could justify that Tashi knows exactly where his opponent is (and what he's doing)... a bull rush attempt just seems strange. :P<br/><br/>But this was just what sneaky Shiro was trying to do... buy himself enough time to do some more trickery, but just in case someone tried to pull something, he popped a squat on the Guard's body until his next turn came around. So no take-backs. ;)<br/><br/>Both the smoke cloud and the poison gas cloud will expand at the end of Shiro's turn.
