A Callback to the Original
In The Incredibles 2, the unlikeliest of friendships form when Bob Parr (Mr. Incredible) asks Edna Mode to babysit Jack-Jack while he gets some much-needed rest. At first, she’s understandably apprehensive about watching a baby, but she immediately learns about his numerous powers and is immediately charmed.
In a later scene, she describes to Bob that Jack-Jack really enjoys listening to Mozart. Now, why is that? It couldn’t possibly be due to the fact that his former babysitter, Kari, played Mozart for him, could it? Of course, it is! Did listening to Mozart make him smarter? We’re not sure, he was still too young to know for sure.
