With Felicity turning to Ray Palmer for some help on her tooth problem, we get to see the recently resurrected Atom getting his hands dirty once more. What was the most WTF about this particular moment was the use of the name Wolfman Biologics as the lead that Ray finds. For long-time comic book fans, that name will have instantly registered as being a nod to the one and only Marv Wolfman. In terms of Arrow-related characters, Wolfman actually created both Deathstroke and Brother Blood, whilst his other notable creations are the likes of Blade, Nova, and Cyborg. This isnt the first time that Arrow has made a point of referencing a member of comic book royalty, and moments like these are always nice Easter eggs for eagle-eyed fans.
