the Whistle batman comic isnt all that in charectar or super well-written but they did go off with having the riddler hang out at a party and solve a rubix cube there in a genuine attempt at a party trick. he changed his last name to nigma. his friend still calls him his old last name. he used to be addicted to vauge drugs. his name on his appartment is w. churchill bcz of the "mystery wrapped in an enigma" thing. damn. that is some riddler.
