No matter what it was, did he learn from it? That's what matters in my book. If he was older, I might care more about the specifics of what he did since I think a lot of people get too comfortable with the lies they build around themselves and appearances they need to keep up, especially professionally. But he's young and he's learning how to hack it in two industries where going at it alone is both rewarding and daunting, and of course you'll mess up somewhere, especially when you have much less experience, both professionally and in life.
That said, if it was something more malicious than what you mentioned, then it would be worth looking into.
