Episodes focusing on the team members in a crime procedural are either the best or worst of instalments. Luckily for Scorpion fans this one falls into the former camp. The O’Brien family and entire Scorpion unit are stuck in a hospital in the grips of a deadly infectious outbreak. Can they figure out how to stop it before they all drop dead? Given this isn’t a finale, it’s safe to assume the answer is yes but it’s an exciting ride anyway.
