Dominated

This is kinda gray area...

I believe your allies remain your allies even when you're dominated.

The condition doesn't mention the target switching sides even though they can be made to attack one of it's own allies.

Dominated

While a creature is dominated, it can’t take actions. Instead, the dominator chooses a single action for the creature to take on the creature’s turn: a standard, a move, a minor, or a free action. The only powers and other game features that the dominator can make the creature use are ones that can be used at will, such as at-will powers. The creature also grants combat advantage and can’t flank.

Hmmm...If there were two street gangs fighting, and then during the middle of the fight, a large number of police in riot gear showed up, then the leaders of the two gangs both yell to "get the cops", then the gang members that were enemies a moment ago would suddenly become allies.

Alternately, a "mole" is with the party of PC's, posing as the PC's guide. The mole actually fights to the best of thier ability in all the battles until the party gets to the enemy encampment. When the party attacks the encampment, the mole suddenly turns on the party and becomes an "enemy" where they were an ally before. It would be unthinkable that in the earlier encounters, powers that only affected enemies would after the mole also, revealing the mole's dual nature.

The classification of ally or enemy is subjective and dynamic and as such, I would think that a dominated PC who is actively trying to kill the party would not be treated as an ally (hmmm...does this mean you can't heal them as you can only heal allies). Flanking and other complication arise...

Can the player choose with the use of each power if the dominated PC is an ally or not? Discuss...

From the May 2010 Update:

Dominated

Page 277: Replace the bullet points in the dominated condition with the following bullet points. These revisions add clarity to the dominated condition.

✦ You can’t take actions. Instead, the dominator chooses a single action for you to take on the creature’s turn: a standard, a move, a minor, or a free action. The only powers and other game features that the dominator can make you use are ones that can be used at will, such as at-will powers. For example, anything that is limited to being used only once per encounter or once per day does not qualify.

✦ You grant combat advantage.

✦ You can’t flank.

In addition, use the following clarifying text:
In spite of this condition, the creature’s allies remain its allies, and its enemies remain its enemies. (Thus, if the dominator makes the creature attack one of its allies, it does not attack an ally of the dominator.)

If the dominator tries to force the creature to throw itself into a pit or move into some other form of hindering terrain, the creature gets a saving throw to avoid entering the terrain.
