"you might think it's a pun" are you not going to explain the pun or does his real name sound a lot like "rookie"
That said, i hope he got some kinda restraining order or strict contract to where his dad can't beg him for money now that he's rich and famous assuming he didn't die by the 'smog' spirit or so
Although the 'entering someone's body', did he take over someone who died?
