Hawk and Dove. Pre-Crisis, they were Hank and Don Hall, brothers. This New 52 version is post-crisis, so Don is dead, and the new Dove is a woman, Dawn Granger. There's a lot of tension between them–Hank hasn't accepted Dawn as a substitute for his brother, and Dawn has a secret she's not telling him, related to his dead brother.

Hawk and Dove stop an airplane that a terrorist had loaded with some sort of zombie and and aimed at the capitol. Later, said zombie turns up, and someone unknown grabs it, saying "–but to me, you smell like dinner. You smell like… Hawk & Dove." Probably an enemy? Many unanswered questions, here.
