Continuing with the slightly stalkerish actions of Oliver Queen here, it was certainly a WTF moment to see Ollie obtain a hair sample from his potential son. Seizing the moment when a cap falls onto the floor, Oliver picks the hat up whilst covertly nabbing himself a stray piece of hair. Sure, this was all in order for him to run a DNA test to discover if he really is Williams dad, but this act could just as easily be viewed as just a little creepy and a tad invasive.
