Well, it's happened.
I was constantly worried about it, especially when Josslyn went from Fat-Headed to Elementary-Aged and Super Blonde. I just figured that when the adorably expressive Braden Walkes vacated the role of Cameron, it would be because the show was going to SORAS him, not just...replace him randomly, with someone about his exact age. I am crossing my fingers that he exited under adorable circumstances, like there was some cute little extracurricular activity that gave him a major scheduling conflict. Like, "Oh, man, I'd love to film a little scene with Laura, but I have karate class and then archeology club! Darn!"
