Teen Titans #33

In the wake of the Terminus Agenda and Crush's first encounter with Lobo, the Teen Titans begin again at Mercy Hall with a new mission and a new lease on life. But just when they catch their first break in ages in their hunt for the Other, Robin confirms that the person who let his prisoners escape...was one of his teammates. As Robin's hunt for the mole begins, Lobo accepts a gift from Lex Luthor...and an unholy alliance is born!
