Most of these sound about right. Still looking forward to seeing how "high school band bass and vocals" will eventually lead to "first man on Mars". He seems a bit young to be into David Bowie.
Other than that, does the implication that both Kari and TK have become popular with the opposite sex suggest shipping shenanigans? Maybe along the lines of "I have eyes from everyone, but only eyes for you"? Because that's where that could be leading. I'm not big into shipping, but I feel like that's the pairing that everybody's hoping for.
Finally, Joe's profile is missing a third sentence. It should simply read "also, action hero".
