Sneak peeks



  • Mick suggests Snart steals compulsively, as he refers to him as a kleptomaniac.
  • Kendra gains Hawkgirl's signature weapon - the Nth metal mace, by melting down the bracelet belonging to her original self and pouring it over Carter's mace.
  • Ray uses a temporal engine to reverse the Dwarf star alloy of his suit, allowing him to grow into a giant. This seems to have been taken from the Marvel Comics character, Ant-Man, who can decrease and increase his size in a similar matter.
