Some television critics were welcoming towards the introduction of Spencer's identical twin sister. Gavin Hetherington of SpoilerTV enjoyed Alex's reveal as "A.D." and her connection to Spencer, stating it was "actually well done." Yana Grebenyuk of TVFanatic echoes the same sentiments of praise, writing that "Alex delivered above and beyond what a Spencer twin could have actually turned out to be. She was truly everything A.D. should have been, including ruthless and ready to kill anyone in her way."
