Jella

Jella was a batarian who helped Skarr and several Blue Suns operatives to access the Dah'tan manufacturing company by closing down the security systems. However, they came at an unexpected time for Jella; and she was forced to hide in a ventilation shaft while hearing her former colleagues being killed. After hiding for a while, she makes a desperate plan. Miraculously, she escaped minutes after Skarr has left and wired the building with explosives. She is put into a comatose state by the blast and is the only survivor. Rescue teams discover her body and Saren is with them. Later, in hospital, Saren questions her whilst she is still in a critical state, and then, afterwards (though she would of made a recovery) he shuts down her machinery.
