Lol yes he remembers the other Captain. And secretly he would agree since Cedric is practically a saint in Hufflepuff.
So they were on the same team for awhile too. Zach probably teases him about being a deserter. But that also helps me think of what the dynamic is for that team considering Zach is the only one in play atm xD!
While they were teammates, they probably went to a lot of parties together then. And just admit it, Roger wants to be loved by everyone: women and men. xD!
