Did they think we wouldn't notice? Because we noticed. Swapping out actors happens for a variety of reasons whether it be conflicting schedules or ageing an actor out à la The Crown. I still appreciate, though, when there is an acknowledgment of said switch (a personal favourite of mine is when they changed actresses for the little sister, Morgan, in Boy Meets World and she quips upon her first entrance, "That was the longest time out ever!"). I digress. We noticed, Riverdale.
