Dr. Kyle Sommer (Matt Long) is one of several new faces introduced in Season 2. He's a charming Texan, toxicologist and the newest member of the CDC team. Kyle missed all the Season 1 madness, but what he experiences on the island will change him in much the same way as last season's survivors.
Major Sergio Balleseros: There are people in the Army, myself included, who are wondering if this outbreak was an accident. Dr. Doreen Boyle: You think Hatake did this on purpose? Why would he do that?
