Brett Dalton's New Villain Revealed

Ever since the winter finale, fans have been speculating as to what that worm that crawled inside Ward's corpse was. Yesterday, at Wizard World Portland, Elizabeth Henstridge revealed that the creature is part of Hive. Hive is an amalgamation of dozens of worm-like parasites created by Hydra which can take on a gestalt consciousness. It also has the capability to take over a host body, which is seems to have done with Ward.
