So I recently rewatched the movie and something is bothering me. When the Srkulls arrived on Earth, there were four of them. At the Blockbuster, there was one who replaced Coulson, who died, and the one on the train (who I believe was Talos) who escaped either way. Later, there were two at Maria Rambeau's house, one of whom died in the escape. What happened to the fourth Skrull?
