Rescue in Bahrain

The Battle of Manama was caused by the Inhuman Katya Belyakov and the misleading of her powers.

History
S.H.I.E.L.D. takes notice of Eva Belyakov's activities and tracks her down to Manama. A team led by Phil Coulson and Melinda May is dispatched to analyze Belyakov for the Index; they are unaware of her daughter's involvement or powers. Eva and Katya assume control of a group of gangsters and hold the entire S.H.I.E.L.D., minus Coulson and May, hostage within a warehouse. May ventures into the warehouse alone and crosses off the controlled gangsters and Eva. Katya reveals herself to May and nearly uses her powers to kill the subjugated S.H.I.E.L.D. team, forcing May to shoot her dead. For her role in saving them, the S.H.I.E.L.D. team gives May the nickname "The Cavalry", a moniker she grows to despise.
