metamorphosis into a teen as witnessed on a road trip

Something else happened on our drive to Florida besides Coach going all granny on me and my driving.  Reg became a teenager right before our eyes. No, it was not his birthday.  He turned 13 in January. You remember, the no gift birthday?

CLUE #1 of how I could tell my little boy had shed his little boy-ness:  His voice changed somewhere between when we backed out of the driveway and when we hit the palm lined expressway in Florida.  Like in the blink of an eye!

not sure if you can see the odd coloring
of Mini's legs.  Bright red mixes
 with swishes of lily white.

Me, waking up from a little snooze in the car: 'Who got in the car while I was sleeping? Who is that talking like that in the back of the minivan? I do not recognize that voice. What just happened?' I mean, I was a little groggy, but his voice change was that sudden and drastic.
CLUE #2: Reggie's appetite is now bottomless. Some background: Reg is a kid that is known to throw up pretty regularly after parties or sleepovers - so maybe his appetite has always known no bounds, but he could not handle overload initially. Or, we are in deep denial and he really has celiac disease. That would suck, so we are better off in denial. I cannot cut a 13 year old off of sheet cake and mountains of cereal. I admit that his fixation on food has been ramping up a bit lately- not just on the trip (not the eat till I vomit ramp up - that was mostly reserved for parties). It became more obvious on the road when our well-stocked pantry was back home in our unfinished kitchen.  

CLUE #3: Reg's sense of humor slapped us in the face with a steady stream of wise-ass, goofy remarks - the kind that only a teenager would make.  Half the time we shrugged and looked at each other like, ‘What?’ At times our 'what' was in reference to Reg acting stupid, the rest of the time it was because Reg has a new marble-in-my-mouth form of speaking.  His comments and jokes consisted of a confusing mumble jumble of nonsense.

I was anxious for Eddie to arrive home from Europe thinking he would literally stop dead in his tracks and say, ‘What happened to Reg’s voice?’  It is that dramatic of a difference. Ed has not commented yet. Jetlag? Fixation on choosing a college?

CLUE #4: This one might not be a teenage thing, but based on Reg's sunscreen issues, I think I am on to something. Reg put on sunscreen. Coach applied it to his back.  Reg claims to have reapplied. This 13 year old with the new voice spent more time in the water than the rest of us, because we don’t all appreciate the adrenaline rush supplied by hypothermia.  (Each day the water got a little bit more tolerable as the days became warmer). Anyway, we wonder if maybe he hopped in the surf too soon after slathering himself with sunscreen? Or, is it a telltale sign of a teenager?

What happened to this guy?!
(update - he recovered after a few days)

The first day, Mini suffered some oddly shaped burns on the back of her legs. Results of lazily rubbing sunscreen (or maybe rubbing is too generous a term) haphazardly across her legs. She's a teenager too, so maybe their frontal lobes just isn't developed enough to focus on SPF.

The girls were both jealous of Reg after that first day claiming that he has better tanning capabilities.  

Well, the next day is when Reg either rubbed the protecting layer off with a towel after swimming or dove in too soon. His nose skin started oozing a strange orangish gel. His eyes swelled up. Now my deep-voiced teen started to resemble a puffy faced helpless infant.
