With the Hive's walls breached, Alex Mercer charges in to confront Elizabeth Greene. Alex questions Greene about his sister's whereabouts and what was Greene. However, her answers do not satisfy Mercer and he is attacked by Greene. During this skirmish, Alex injects the cure Blackwatch had used against him. Greene's biology rejects the cure, and the biomass she regurgitates forms into a new form of infected Hunter.
