ALIAS

The gang were on mission in Algeria. Sydney met with a guy who was offering her a 'weapon'. He swallowed it as it was the only way he could smuggle it. Fight ensues, man with swallowed weapon gets knocked around. The tiny vile of ICE-5 begins to leak in his stomach and he slowly freezes - or crystalises. As the gang try to load his freezing body into the van, he gets shot and literally shatters.

Sydney and the gang were sent to a Montenegro hospital were they believed they were manufacturing ICE-5. A doctor there was helping to perform tests of ICE-5 on patients in a restricted area of the hospital. The operation seemed to be headed by the doctor's brother.

Vaughn went undercover as a priest and tried to help the doctor get away from her brother. They bonded, he spilled his guts to her about Lauren when he was trying to get her to turn against her brother. She betrayed him. Her and the brother took him hostage. She almost injected him with ICE-5. Sydney saved the day, brother accidently stabbed sister with the ICE-5 needle. She froze. She died.

Oh, and Sydney's sister was trying to figure out who the baby was that her mother was holding in an old photograph. Jack told her Irena told him it was her niece.
