Answered: Question regarding possession

Here is a picture regarding the possession of 3 different balls. Ball 1 (on the far left) is clearly possessed, as it is in contact with a concave surface of the robot. My question is whether balls 2 and 3 (ball 3 is in the front and ball 2 is on the far right) are possessed as well. Ball 2 is not in contact with a concave surface of the robot, however, it contacts both the robot and ball 1, and ball 1 creates a concave shape that could hold ball 2 in place. Ball 3 is not in contact with the robot at all, but it could be held in place by balls 1 and 2.

Balls 2 and 3 would not be considered to be possessed.
