@Teoinsanity Main event has been that Fury received a call from a research facility which suggested they were being attacked and ended in screams and a roar (pretty grim!) which Fury played to the team and asked them to help him. Also he just revealed that the facility had been working with Banner DNA.
That's a very simplified version but I don't think there are pages and pages to catch up on so you should be able to find the relevant posts :)
