Felicity Smoak and Ray Palmer put their enormous brains together to solve a Damien Dahrk-related mystery in new clip from tonight's "Brotherhood" episode of Arrow.

Felicity tries to convince Ray to declare himself undead and to take back his company. For whatever reason he wants to change the subject and focus on the reason she called him over which is to analyze a tooth that is missing half of its genetic markers.
