in the first movie when an agent is killed he morphs back to the person who they are in,
e.g. when smith,jones and brown get the mingun on them they morph back into the guards.
but in m2 when an agent gets killed they don't morph back.
e.g. agent gets kicked off the truck by morpheus, but dosen't morph back when he hits the car.
Agents MORPH back to their original position before the body that they have swaped with dies.
Not sure if an Agent could morph back if death is instint. Not sure if an agent has "died" instantly as of yet. In the event of the trucks colliding, the Agents could easily morph out before the trucks hit.
Also, not sure about how many Agents are left. Did we ever know how many there were in the beginning?
I don't think there's any reason to believe there are only 3 agents. That's never been hinted at. They probably just travel in groups of three. There ARE more trouble-making rebels than Neo, Trin and Morpheus, so...
I think the back-morphing just happens automatic.
