Rok would still be considered an adolescent, if the lore from Star Trek: New Frontier applies, from which her species was largely fleshed out.
At that age, she would be very gruff and moody, only after molting in her 30’s (I think?) would she regain her more bubbly personality.
Dude, you’re missing out then. I was dubious going in, but Time Lord Wesley was the absolute delight I didn’t know I needed. Wheaton’s performance was probably leagues better than in TNG.
