The sketch is of Winifred and its here where she steps forward as a leader within the team as Wesley deals with what to do with where prophecies are pointing. In other words, its a lot of events in one season. Angel is to be a father which was completely left field, but the writers worked it out. It has a great flow from season 2 and sets everything up for a rocky season 4. In my opinion, it closed a few stories from season 2 and planted for season 4. Anything to do with the birth before and after just sent Angel's character in circles.
