7. Hawkeye's Farmhouse
Whether Avengers Tower is destroyed or Ultron compromises the team's technological resources to the point where they're forced to go off the grid and regroup, they will head to Hawkeye's farm somewhere around this point. Perhaps his wife will be introduced at this point just like in The Ultimates, but expect to see Clint Barton fleshed out here either way. How long they'll stay here is hard to say, but piecing together the promos and trailers, expect to see Nick Fury make his grand return somewhere around this point. Either he or Captain America will probably deliver a rousing speech to motivate the team, while Ultron's attacks will no doubt catch their attention as a news report plays on TV in the background.
