Over the past few days, I've come to realize that Michael is an exceptionally clever kid. His composure and insight far surpass that of the average adult; at least, he's got me completely stumped.
After pondering for a moment, Michael slowly reached out both hands and readjusted Betty's tube top back to its original position before once again making a move towards Betty's lower half.
Watching all this, I couldn't help but admire the meticulousness of this kid, Michael. If he had touched Betty's lower half earlier and Betty had woken up at that moment, Michael wouldn't have had the time to "clean up" the scene. He could instantly lie back down and pretend to be asleep, but the misplaced tube top would have given him away.
By putting the tube top back in place, although his eyes held a hint of regret, he chose to ensure a foolproof plan over taking risks.
