ah, now i see; so this Bob character's a super hero with ninja and flying powers...very clever, for a moment i was worried that he was just your avergae little guy...but, NO! he is not a mere mortal, he is MAGIC!
....I will actually dance like crazy if i just guessed right, but i doubt that.
Anyhoo: one thing that i've never been too sure on is the American schooling system. I'm not sure i understand the grades and sophomore, senior, freshman stuff. And also, junior high, middle school and high school, in Scotland all we have is primary and secondary, or high school. You start High school when you're 11.
[wow, long winded] what my point is, is that i'm asking you what age an eighth grader is? [and yes, i'm aware i sound like an idiot]
WHO TOLD YOU ABOUT BOB'S SECRET IDE-
...this is awkward...
Eighth graders are 13 at the beginning of the year, unless they've either been moved up or held back a year.
