I can't help but think the twins are gonna get caught again, to be totally honest. Hopefully it's Tara that catches them, because I don't think Jack's gonna be able to smooth things over if they're caught by their parents again.
As far as Jack.. he's lived, from what I can gather, lived a pretty charmed life up until this particular school year, and then all hell's broken loose- pretty much literally. Since September, he's been in 3 fights with Craig (if you count the wrestling match in Gym class), almost got into another fight at Jessica's party, the "Clash of the Titans" (Fight with Brad vs. the whole bunch), watched his former Gym coach shoot himself, accidentally kiss his cousin, pushed away Amanda's sexual advances, had to deal with Mom and Dad finding out about the twins, dealt with Brad's scheming to bed Amanda, found out about Jeff, etc etc etc. God knows I've forgotten stuff, but it's been 3 months, give or take, since this story started. That's a hell of a rude awakening. As far as him whining about his life should be roses, I honestly can't blame him one bit, but... he's not just whining. He's trying his best to deal with everything that's being thrown at him, which, if you think about it, is a HELL of a lot for ANY 16 year old guy to have to deal with. Hell, it's a lot for anyone, regardless of age.
Also.. fever and vomiting..... is Jack sick?
