Countdown #18

Countdown - Safe House / The Origin of Dr. Light
On Earth-51, Ray Palmer is living the life he feels he deserves. He and all his friends have retired from the superhero business as there is next to no crime on the world. They congregate at his and Jean's house to celebrate Christmas but are disturbed by the appearance of the Challengers. Confronted by them, Ray tells his friends of how he came from a different Earth and traveled the Multiverse until finding Earth-51 and his counterpart who died during an experiment. He took his place, continued his work and married his Jean Loring. Having found Ray Palmer at last, Bob the Monitor attempts to kill him. In outer space, Eclipso returns to Mary's body intending to take her power. Mary has been playing possum, however, and attacks her.
