Plot Summary
During the middle of a Hellsing raid on a castle, the SAS's 22nd Regiment arrives in their Counter Revolutionary Warfare (CRW) gear and orders them to pull back. The SAS squads in the castle are later converted into FREAK monsters by an unknown party. Meanwhile, Alucard begins to track the Vampire Incognito. Shortly after, Integra's "sister" Laura arrives, but Seras cannot shake the feeling that something is wrong. Her suspicions are proven valid when Laura is revealed to be a baobhan sith, a Scottish vampire with powerful hypnotic abilities sent to assassinate Integra. Seras attempts to stop her but is restrained by Walter. During their confrontation, Incognito's mocking comments alerts Alucard to Integra's peril as he returns to kill Laura, freeing Walter and Seras. Integra stabs herself in the neck to remove the tainted blood in her veins and collapses.
