Legend
If he'd succeeded on the Perception check, he'd be awake (not unconscious), so he would be able to take actions.
Actually, that's my point - if a successful Perception check (meaning he detected the ambush) means that he is awake and able to take actions, then the Foresight ability (which means he detects the ambush) should also mean that he is awake and able to take actions. Basically, it's a supernatural sense that makes him aware even when his regular senses fail him.
