Since Ray Palmer debuted in Arrow, weve been constantly reminded of just how much of a genius the head of Palmer Technologies is. Hell, he even went as far as to create his own super-suit to become the hero known as The Atom. Still, it was a nice, humourous moment to have the renowned Ray Palmer not even a footnote in the career of Martin Stein. During their first moments on the Waverider, Palmer gushes about the ship and about a paper he wrote when he was a pupil of Steins years ago. As cool and as nonchalantly as you like, Stein simply makes comment that he doesnt even remember teaching Palmer. Thats certainly a kick in the nuts, and to the ego, of the ever-flawless Ray Palmer.
