Hrm, being held back a year works for Luck. I think I'll make him held back during ~7th grade or the start of highschool or something. So they're in 11th grade then?
Gosh, I didn't think about that ><. Hmm, if in 11th grade they're late starters, or flunked or something--since it's november and all (in 11th grade people turn 17 during the second half after new year's eve...). If in 12th grade they're normal.
