"When Rogue tried to absorb the Surfer she was caught in some kind of feedback effect, that knocked her over. Actually she did not absorb any of Norrin Radd’s cosmic power, but she could tell that he had good intentions."
Rogue tried and failed. Why? 'Cause Norinn has no dick or juice box, her powers work only on these types xD
