Does Drago love Wavern

He sure does. In fact, they even knew each other in more ways than one before they met the brawlers. There are 3 key pieces of evidence that Drago loves Wavern-1: In episode 35, Wavern called him Dragoruny and said they had their history together-Gross. 2: In episode 36, right before Dan was leaving for Runo's house, Drago said he had "plans of his own", which was basicly a date with Wavern. And 3: in episode 37, Wavern came to see the battle between him and Skyress. Than Drago got hit pretty hard with teasing after that. So there's your answer. Gross.
