7 seems about right for Vincent and Jas--I have kids that age, and it's pretty much right in line with how CA has constructed Vincent and Jas. That said, I'd place all the parents as being anywhere from 5 to 10 years older--all at least in their late 40s for Jodi and Kent, who would probably be about 20-ish years older than Sam. The other parents, especially Robin and Demetrius, don't strike me as the "young parent" types; Robin would not have been a carpentry apprentice in her early 20s with a toddler running around, and Demetrius seems to have a PhD, which means--especially with his personality--he would not have been putting personal relationships at the forefront until at least his late 20s and probably early 30s. With that, I'd put Robin and Demetrius in their 50s.I actually agree with most of @Uzzlegorf's list above, a lot of them line up with my imagination. I think Alex is the same age as Haley (23) and Sam and Sebastian are the same age, since then they would be in the same grade at school (24) Vincent and Jas seem a liiiittle too immature to me to be 10, so (7) Penny seems like she in her twenties, especially considering she's the "love interest" for Sam, (24) and Maru is Sebastian's YOUNGER half-sister, it would make no sense to her to be OLDER than him (20)
