FANCASTING
This fan casting is based on their appearances in earlier seasons when the characters were younger (they are college-aged at the moment). I chose these face claims not only because of their looks and the vibes but also because they're peers (at least Paige and Griffin are). I believe it's important when two actors are playing love interests to be around the same age.

Karis Cameron as teenage!Maddie
Griffin Gluck as middle school!Ryan White
