Yeah well I found the most exciting of those possibilities: Alistar's true personality that was forged from his life's best memories (the training with his mentor), his will to keep that part of himself alive left a gap in the disease's progress. Unlike other infected, he'll have that special side that will break the disease when the disease and Alistar's made up-will are forced to be put down (exhaustion could cause that). So we could make a scene where he acts how he truly is, instead of a boring faint. If he simply faints, the hatred will grow and we won't have much opportunities to bond the two/it'll be hard.
