Ai goal injured follow

This entity was originally used in a portion of Episode 2 when Alyx got injured. It would make Alyx occasionally flinch, use special "injured" animations for most tasks, and tell the player to slow down if they get too far ahead of her. The entity does not seem to function at all in its current form.

This developer commentary line from Quintin Doroquez on is most likely referring to this entity:
 * "Early in the development for this level, we used an animation for Alyx that showed her as clearly injured as she ran along behind the player. This really slowed her down, however, and playtesters did not enjoy waiting for her to catch up, or going back to retrieve her. To address this, we started her recovery in the preceding map to make sure she was healthy enough to run at regular speed before reaching this area."
