Grudge

Players can form grudges against other players. When a player forms a grudge, a screen will be displayed to them that says,
 * You now win if and only if [Enemy] is imprisoned. Try to convince your fellow players that [Enemy] is a double agent.
 * Just look at [Enemy]'s ugly face. Nothing matters except their utter humiliation!
 * You hate: [Enemy]
 * You hate: [Enemy]
 * You hate: [Enemy]

If the player forms a grudge against another player, their win conditions change. They no longer have allegiance to their team against the other. Rather, their goal becomes to imprison the person they hold a grudge against, regardless of their membership VIRUS or The Service. If this player is not imprisoned, they lose.
