That is a tad complicated, I think.
Are you saying he wanted to be found out?
He aught as well have been playing on his Gameboy,manipulating the buttons as he did the characters in this drama. Julie couldn't read him,Sheila was in her own world and the twins' heroic selflessness shone through their every action,inheriting as they did the best in both parent. Jeremy thought he could control Julie with threats if necessary and use his charm on cousin Ann to avert suspicion,but the game was played from the moment the Police arrived at the White House,the charade continuing as they progressed to Goldhanger with Jeremy centre stage for maybe the only time in his life before the trial,where he similarly found a macabre pleasure as he does to this day with his hankering to pull the wool over anyone's eyes who ventures too close to him.
