[Theory] Cynthia’s Age (May contain spoilers)

Cynthia is most likely in her twenties, maybe a bit younger than Steven. Steven is 25 but already give off an "old guy in Pokemon" vibe. Plus in the game she has a very young sister, and her granny is still alive and seemingly healthy. I disagree that she might be in her 30s.

What do you think and why?

This is a healthy discussion by the way, so no arguing or assailing any other user is permitted.

Just like Steven, Cynthia seems to act a lot more mature than you'd expect for her age, but I don't know if she's younger than him. I always figured she was somewhere between 28-33, with her grandmother probably in her mid 70s.

We might be able to guess her age a bit better if we knew anything about her parents, because it's very possible that her sister could have a different mom or dad, which would explain the age gap (but then again, my aunt is 20 years older than my dad, so who really knows).
